100MHz to 2500MHz, 45dB RF Detector in a UCSP
General Description
The MAX4003 low-cost, low-power logarithmic amplifier is designed to detect the power levels of RF power amplifiers (PAs) operating from 100MHz to 2500MHz. A typical dynamic range of 45dB makes this logarithmic amplifier useful in a variety of wireless applications including cellular handset PA control, TSSI for wireless terminal devices, and other transmitter power measurements. This logarithmic amplifier provides much wider measurement range and superior accuracy than typical diode-based detectors. Excellent temperature stability is achieved over the full operating range of -40C to +85C. The MAX4003 logarithmic amplifier is a voltage-measuring device with a typical signal range of -58dBV to -13dBV. The input signal is internally AC-coupled by an on-chip 5pF capacitor in series with a 2k resistance. This highpass coupling, with a corner at 16MHz, sets the lowest operating frequency and allows the input signal source to be DC grounded. The MAX4003 also features a power-on delay, which holds the detector output (OUT) low for approximately 5s to ensure glitchless controller output. The MAX4003 is available in an 8-bump chip-scale package (UCSPTM), an 8-pin MAX package, and an 8-pin thin QFN package. The device consumes 5.9mA with a 3.0V supply and only 13A when the device is in shutdown. o Complete RF Detector o Frequency Range from 100MHz to 2500MHz o Input Range of -58dBV to -13dBV (-45dBm to 0dBm into 50) o Fast Response: 70ns in 10dB Steps o Low-Current Consumption: 5.9mA at VCC = 3.0V o 13A (typ) Shutdown Current o Available in 8-Bump UCSP or 8-Pin MAX and Thin QFN Packages

The bypass capacitor must not share its ground vias with any other branches.
Detailed Description
The MAX4003 logarithmic amplifier comprises four main amplifier/limiter stages, each with a small-signal gain of 10dB. The output stage of each amplifier/limiter stage is applied to a full-wave rectifier (detector). A detector stage also precedes the first stage. In total, five detectors, each separated by 10dB, comprise the logarithmic amplifier strip (see Functional Diagram). A portion of the PA output power is coupled into RFIN of the logarithmic amplifier detector through a directional coupler, and is applied to the logarithmic amplifier strip. Each detector stage generates a rectified current, and these currents are summed to form a logarithmic function. The detected output is applied to a high-gain transconductance (gm) stage, which is buffered and then applied to OUT. OUT is applied to an ADC typically found in the baseband IC which, in turn, controls the
PA biasing with its DAC output (Figure 1). In a control loop, the detector output voltage range is approximately 0.36V for the minimum input signal, -45dBm, to 1.45V at the maximum input range, 0dBm. The logarithmic intercept of the detector output with respect to the RF input can be obtained by drawing a best fit line of the Output Voltage vs. RF Input Power graph. The logarithmic slope is defined as the change in the detector output vs. the change in RF input. The MAX4003 slope at low frequencies is approximately 25.5mV/dB. Variation in temperature and supply voltage does not alter the slope significantly, as shown in the Typical Operating Characteristics.
Applications Information
Filter Capacitor and Transient Response
In general, the choice of filter only partially determines the time-domain response of a PA detector loop. However, some simple conventions may be applied to discuss transient response. A large filter capacitor, CCLPF, dominates time-domain response, but the loop bandwidth remains a factor of the PA gain-control range (see Typical Operating Characteristics). The bandwidth is maximized at power outputs near the center of the PA's range and minimized at the low and high power levels, when the slope of the gain control curve is lowest. A smaller valued CCLPF results in an increased-loop bandwidth inversely proportional to the capacitor value. Inherent phase lag in the PA's control path, usually caused by parasitics at the OUT pin, ultimately results in the addition of complex poles in the AC loop equation. To avoid this secondary effect, experimentally determine the lowest usable CCLPF for the power ampli-

fier of interest. This requires full consideration of the intricacies of the PA detector control function. The worst-case condition, where the PA output is smallest (gain function is steepest), should be used because the PA control function is nonlinear. An additional zero can be added to improve loop dynamics by placing a resistor in series with CCLPF.
UCSP Reliability
The UCSP represents a unique package that greatly reduces board space compared to other packages. UCSP reliability is integrally linked to the user's assembly methods, circuit board material, and usage environment. The user should closely review these areas when considering use of a UCSP. This form factor may not perform equally to a packaged product through traditional mechanical reliability tests. Performance through operating life test and moisture resistance remains uncompromised as it is primarily determined by the wafer fabrication process. Mechanical stress performance is a greater consideration for a UCSP. UCSP solder joint contact integrity must be considered since the package is attached through direct solder contact to the user's PC board. Testing done to characterize the UCSP reliability performance shows that it can perform reliably through environmental stresses. Results of environmental stress tests and additional usage data and recommendations are detailed in the UCSP application note found on Maxim's website, www.maxim-ic.com.
MAX4003
Waveform Considerations
Although the input level of the MAX4003 is specified in dBm, the logarithmic amplifier actually responds to rectified voltage signals rather than a true RMS power. It is important to realize that input signals with identical rootmean-square power but with unique waveforms result in different logarithmic outputs. Differing signal waveforms result in either an upward or downward shift in the logarithmic intercept. However, the logarithmic slope remains the same.
Layout Considerations
As with any RF circuit, the MAX4003 circuit layout affects performance. To ensure maximum power transfer between 50 sources and the MAX4003 input, suitable matching networks should be implemented. The VCC input should be bypassed as close as possible to the device with multiple vias connecting the capacitor to the ground plane.
