MAX4003
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 -40°C to +85°C.
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 2kΩ 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 5µs to ensure
glitchless controller output.
The MAX4003 is available in an 8-bump chip-scale package (UCSP™), an 8-pin µMAX package, and an 8-pin thin
QFN package. The device consumes 5.9mA with a 3.0V
supply and only 13µA when the device is in shutdown.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

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

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-

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 50Ω 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.
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.

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.
