general description the max2039 high-linearity passive upconverter or downconverter mixer is designed to provide 7.3db nf and a 7.1db conversion loss for an rf frequency range of 1700mhz to 2200mhz to support umts/wcdma, dcs, and pcs base-station transmitter or receiver applications. the iip3 is typically +34.5dbm and +33.5dbm for downconversion and upconversion oper- ation, respectively. with an lo frequency range of 1500mhz to 2000mhz, this particular mixer is ideal for low-side lo injection architectures. (for a pin-to-pin- compatible mixer meant for high-side lo injection, con- tact the factory.) in addition to offering excellent linearity and noise per- formance, the max2039 also yields a high level of com- ponent integration. this device includes a double-balanced passive mixer core, a dual-input lo selectable switch, and an lo buffer. on-chip baluns are also integrated to allow for a single-ended rf input for downconversion (or rf output for upconversion), and single-ended lo inputs. the max2039 requires a nominal lo drive of 0dbm, and supply current is guar- anteed to be below 135ma. the max2039 is pin compatible with the max2031 815mhz to 995mhz mixer, making this family of passive upconverters and downconverters ideal for applications where a common pc board layout is used for both fre- quency bands. the max2039 is available in a compact 20-pin thin qfn package (5mm x 5mm) with an exposed paddle. electrical performance is guaranteed over the extended -40? to +85? temperature range. applications umts/wcdma base stations dcs1800/pcs1900 edge base stations cdmaone tm and cdma2000 base stations phs/pas base stations predistortion receivers fixed broadband wireless access wireless local loop private mobile radio military systems microwave links digital and spread-spectrum communication systems features ? 1700mhz to 2200mhz rf frequency range ? 1500mhz to 2000mhz lo frequency range ? 1900mhz to 2400mhz lo frequency range (contact factory) ? dc to 350mhz if frequency range ? 7.1db conversion loss ? +34.5dbm input ip3 (downconversion) ? +24.4dbm input 1db compression point ? 7.3db noise figure ? integrated lo buffer ? integrated rf and lo baluns ? low -3dbm to +3dbm lo drive ? built-in spdt lo switch with 45db lo1 to lo2 isolation and 50ns switching time ? pin compatible with the max2031 815mhz to 995mhz mixer ? external current-setting resistor provides option for operating mixer in reduced-power/reduced- performance mode ? lead-free package available max2039 high-linearity, 1700mhz to 2200mhz upconversion/ downconversion mixer with lo buffer/switch ________________________________________________________________ maxim integrated products 1 ordering information 19-3468; rev 0; 10/04 for pricing, delivery, and ordering information, please contact maxim/dallas direct! at 1-888-629-4642, or visit maxim? website at www.maxim-ic.com. part temp range pin-package pkg code MAX2039ETP -40? to +85? 20 thin qfn-ep* (5mm x 5mm) bulk t2055-3 MAX2039ETP-t -40? to +85? 20 thin qfn-ep* (5mm x 5mm) t/r t2055-3 MAX2039ETP+d -40? to +85? 20 thin qfn-ep* (5mm x 5mm) lead-free bulk t2055-3 MAX2039ETP+td -40? to +85? 20 thin qfn-ep* (5mm x 5mm) lead-free t/r t2055-3 * ep = exposed paddle. + = lead free. d = dry pack. cdmaone is a trademark of cdma development group. cdma2000 is a registered trademark of telecommunications industry association. pin configuration and typical application circuit appear at end of data sheet. j/00

max2039 detailed description the max2039 can operate either as a downconverter or an upconverter mixer that provides 7.1db of conver- sion loss with a typical 7.3db noise figure. iip3 is +33.5dbm for upconversion and +34.5dbm for down- conversion. the integrated baluns and matching cir- cuitry allow for 50 ? single-ended interfaces to the rf port and two lo ports. the rf port can be used as an input for downconversion or an output for upconver- sion. a single-pole, double-throw (spdt) switch pro- vides 50ns switching time between the two lo inputs with 45db of lo-to-lo isolation. furthermore, the inte- grated lo buffer provides a high drive level to the mixer core, reducing the lo drive required at the max2039? inputs to a range of -3dbm to +3dbm. the if port incorporates a differential output for downcon- version, which is ideal for providing enhanced iip2 per- formance. for upconversion, the if port is a differential input. specifications are guaranteed over broad frequency ranges to allow for use in umts, cdma2000, and 2g/2.5g/3g dcs1800, and pcs1900 base stations. the max2039 is specified to operate over an rf fre- quency range of 1700mhz to 2200mhz, an lo frequen- cy range of 1500mhz to 2000mhz, and an if frequency range of dc to 350mhz. operation beyond these ranges is possible; see the typical operating characteristics for additional details. this device can operate in high-side lo injection appli- cations with an extended lo range, but performance degrades as f lo continues to increase. see the typical operating characteristics for measurements taken with f lo up to 2200mhz. for a device with better high-side lo injection performance, contact the factory. rf port and balun for using the max2039 as a downconverter, the rf input is internally matched to 50 ? , requiring no external match- ing components. a dc-blocking capacitor is required since the input is internally dc shorted to ground through the on-chip balun. the rf return loss is typically 18db over the entire 1700mhz to 2200mhz rf frequency range. for upconverter operation, the rf port is a single- ended output similarly matched to 50 ? . lo inputs, buffer, and balun the max2039 can be used for either high-side or low- side injection applications with a 1500mhz to 2000mhz lo frequency range. for a device with a 1900mhz to 2400mhz lo frequency range, contact the factory. as an added feature, the max2039 includes an internal lo spdt switch that can be used for frequency-hopping applications. the switch selects one of the two single- ended lo ports, allowing the external oscillator to settle on a particular frequency before it is switched in. lo switching time is typically less than 50ns, which is more than adequate for virtually all gsm applications. high-linearity, 1700mhz to 2200mhz upconversion/ downconversion mixer with lo buffer/switch 12 ______________________________________________________________________________________ pin description pin name function 1, 6, 8, 14 v cc power-supply connection. bypass each v cc pin to gnd with capacitors as shown in the typical application circuit . 2rf single-ended 50 ? rf input/output. this port is internally matched and dc shorted to gnd through a balun. 3 tap center tap of the internal rf balun. bypass to gnd with capacitors close to the ic, as shown in the typical application circuit . 4, 5, 10, 12, 13, 16, 17, 20 gnd ground 7 lobias bias resistor for internal lo buffer. connect a 549 ? 1% resistor from lobias to the power supply. 9 losel local oscillator select. logic control input for selecting lo1 or lo2. 11 lo1 local oscillator input 1. drive losel low to select lo1. 15 lo2 local oscillator input 2. drive losel high to select lo2. 18, 19 if-, if+ differential if input/outputs ep gnd exposed ground paddle. solder the exposed paddle to the ground plane using multiple vias.
if frequency hopping is not employed, set the switch to either of the lo inputs. the switch is controlled by a digital input (losel): logic high selects lo2, logic low selects lo1. in order to avoid damage to the part, volt- age must be applied to v cc before digital logic is applied to losel (see the absolute maximum ratings ). lo1 and lo2 inputs are internally matched to 50 ? , requiring only a 22pf dc-blocking capacitor. a two-stage internal lo buffer allows a wide-input power range for the lo drive. all guaranteed specifica- tions are for an lo signal power from -3dbm to +3dbm. the on-chip low-loss balun, along with an lo buffer, drives the double-balanced mixer. all interfacing and matching components from the lo inputs to the if out- puts are integrated on chip. high-linearity mixer the core of the max2039 is a double-balanced, high- performance passive mixer. exceptional linearity is pro- vided by the large lo swing from the on-chip lo buffer. differential if the max2039 mixer has an if frequency range of dc to 350mhz. note that these differential ports are ideal for providing enhanced iip2 performance. single-ended if applications require a 1:1 balun to transform the 50 ? dif- ferential if impedance to a 50 ? single-ended system. after the balun, the if return loss is better than 15db. the differential if is used as an input port for upconvert- er operation. the user can use a differential if amplifier following the mixer but a dc block is required on both if pins. in this configuration, the if+ and if- pins need to be returned to ground through a high resistance (about 1k ? ). this ground return can also be accomplished by grounding the rf tap (pin 3) and ac-coupling the if+ and if- ports (pins 19 and 18). applications information input and output matching the rf and lo inputs are internally matched to 50 ? . no matching components are required. return loss at the rf port is typically 18db over the entire input range (1700mhz to 2200mhz) and return loss at the lo ports is typically 16db (1500mhz to 2000mhz). rf and lo inputs require only dc-blocking capacitors for interfacing. the if output impedance is 50 ? (differential). for eval- uation, an external low-loss 1:1 (impedance ratio) balun transforms this impedance to a 50 ? single-ended out- put (see the typical application circuit ). bias resistor bias current for the lo buffer is optimized by fine tun- ing resistor r1. if reduced current is required at the expense of performance, contact the factory for details. if the ?% bias resistor values are not readily available, substitute standard ?% values. layout considerations a properly designed pc board is an essential part of any rf/microwave circuit. keep rf signal lines as short as possible to reduce losses, radiation, and induc- tance. for the best performance, route the ground pin traces directly to the exposed pad under the package. the pc board exposed pad must be connected to the ground plane of the pc board. it is suggested that mul- tiple vias be used to connect this pad to the lower-level ground planes. this method provides a good rf/ther- mal conduction path for the device. solder the exposed pad on the bottom of the device package to the pc board. the max2039 evaluation kit can be used as a reference for board layout. gerber files are available upon request at www.maxim-ic.com. power-supply bypassing proper voltage-supply bypassing is essential for high- frequency circuit stability. bypass each v cc pin and tap with the capacitors shown in the typical application circuit; see table 1. place the tap bypass capacitor to ground within 100 mils of the tap pin. max2039 high-linearity, 1700mhz to 2200mhz upconversion/ downconversion mixer with lo buffer/switch ______________________________________________________________________________________ 13 component value description c1 4pf microwave capacitor (0603) c4 10pf microwave capacitor (0603) c2, c6, c7, c8, c10, c12 22pf microwave capacitors (0603) c3, c5, c9, c11 0.01? microwave capacitors (0603) r1 549 ? ?% resistor (0603) t1 1:1 balun if balun with dc grounded ports u1 max2039 maxim ic table 1. component list referring to the typical application circuit
