Interface Control
The interface port is designed to use a 20-pin ribbon cable (Figure 1); 10 pins are signal lines, and the other 10 pins are digital grounds. Pin 1 of the interface cable is red. Pin 1 is also designated in silk screen on each of the PC boards.
Detailed Description
The following section covers the EV kits' circuit blocks in detail (refer to the MAX2361/MAX2363/MAX2365 data sheet for additional information).
I/Q Inputs
The single-ended I/Q signals are converted to differential by operational amplifiers on the EV kit. The op amps also provide DC bias to the I/Q input pins of the MAX2361/MAX2363/MAX2365. The EV kits are set up to provide 415mVp-p differential to the IC when used with a 50 source that delivers 1Vp-p into 50. For other I/Q levels, replace R9 and R18 with appropriate resistor values according to Table 2.

For cascade evaluation, an on-board filter is connected between IFOUTH and IFINH. Select these ports by programming IF_SEL to 1. IFINH and IFOUTH are not connected to SMA connectors on the EV kit
IFINL and IFOUTL
For cascade evaluation, an on-board filter is connected between IFOUTL and IFINL. Select these ports by programming IF_SEL to 0. For individual IF modulator and upconverter evaluation, remove R44, R49, R55, R58, and install R25, R33, R34, and R39 with 0 resistors. This connects the IFINL_ and IFOUTL_ pins to the IFINL and IFOUTL SMA connectors. The matching networks are tuned to 130MHz.
*Set R9 and R18 for different I/Q input-source level (baseband waveform taken from the back panel of Agilent's E4433B signal generator).
IFLO
The IFLO output port provides an output signal that is either the IF VCO frequency or the VCO frequency divided by 2, depending on the setting of the BUF_DIV control bit. It can be enabled by setting the BUF_EN bit to 1 in the OPCTRL register.
VBAT/VREG
VBAT supplies VCC to the PA driver circuitry. This may be an unregulated battery voltage. The PA drivers are open collector. Jumpers are provided to enable current measurement to each functional block of the IC (Table 3). VREG is connected to the output of the U2 regulator on the EV Kit. Do not connect an external supply voltage to VREG header.
TANK BYP
The tank bypass port is provided to drive the high-band tank with an external LO source. The VCO_BYPASS bit should be set to 1 to enable this port. Replace C25 with 0.01F AC-coupling capacitor; replace R36 and R70 with 0 resistors; and remove R38, C12, C24, L10, D1, and D2.
REF
REF is the reference frequency input to the RF and IF PLL. The REF port is AC-coupled. Make sure the reference signal has low phase noise.
RBIAS
When resistor R73 is stuffed (typically 10k), a bias voltage may be applied to the RBIAS header to adjust the PA driver bias current. Internal to the IC, pin 12 is set to 600mV. Output linearity or efficiency may be improved by adjusting PA driver current.
LOH
LOH is the high-band RF LO input port. The EV kit is shipped with this port disconnected. To use this port with an external signal source, disconnect the PCS VCO by removing C39 and placing it at location C66.
Layout Considerations
The MAX2361/MAX2363W EV kits can serve as guides for your board layout. Keep PC board trace lengths as
LOL
LOL is the low-band RF LO input port. The EV kit is shipped with this port disconnected. To use this port with an external signal source, disconnect the cellular VCO by removing C40 and placing it at location C65.

short as possible to minimize parasitics. Also, keep decoupling capacitors as close to the IC as possible with a direct connection to the ground plane.
INTF2300 SPI Interface Board
The INTF2300 interface board is used to interface 3-wire SPI protocol from a PC's parallel port to the EV kit. This board will level translate 5V logic from the PC to VCC of the EV kit (typically this will be 3.3V logic). The INTF2300 also provides buffering and EMI filtering. Its absolute maximum supply voltage is 4.6V, limited by the breakdown of the buffer IC. The recommended operating supply voltage range is +2.7V to +3.6V.
