with a 2k?resistance.This highpass coupling, with a corner at 16MHz, setsthe lowest
operating frequency and allows the inputsignal source to be DC grounded. The MAX4003
alsofeatures a power-on delay, which holds the detectoroutput (OUT) low for
approximately 5?s to ensureglitchless controller output.
The MAX4003 is available in an 8-bump chip-scale pack-age (UCSP?), an 8-pin ?MAX
package, and an 8-pin thinQFN package. The device consumes 5.9mA with a 3.0Vsupply
and only 13?A when the device is in shutdown.

The MAX4003 logarithmic amplifier comprises fourmain amplifier/limiter stages, each
with
a
small-signalgain
of
http://doc.xuehai.net/b85732741ed9dda2ddc25eaf1.html10dB. The output stage of each
amplifier/limiterstage is applied to a full-wave rectifier (detector). Adetector
stage also precedes the first stage. In total,five detectors, each separated by 10dB,
comprise thelogarithmic amplifier strip (see Functional Diagram).A portion of the
PA output power is coupled into RFINof the logarithmic amplifier detector through
a direction-al coupler, and is applied to the logarithmic amplifierstrip. Each
detector stage generates a rectified current,and these currents are summed to form
a logarithmicfunction. The detected output is applied to a high-gaintransconductance

In a control loop, the detector output voltage range isapproximately 0.36V for the

detector output withrespect to the RF input can be obtained by drawing abest fit line
of the Output Voltage vs. RF Input Powergraph. The logarithmic slope is defined as
the changein the detector output vs. the change in RF input. TheMAX4003 slope at low
frequencies is approximately25.5mV/dB. Variation in temperature and supply volt-age
does not alter the slope significantly, as shown inthe Typical Operating
Characteristics.
Filter Capacitor and Transient Response
In general, the choice of filter only partially determinesthe time-domain response
of a PA detector loop.However, some simple conventions may be applied todiscuss
transient response. A large filter capacitor,CCLPF, dominates time-domain response,
but the loopbandwidth remains a factor of the PA gain-control range(see Typical
Operating Characteristics). The bandwidthis maximized at power outputs near the

increased-loopbandwidth inversely proportional to the capacitor value.Inherent
phase lag in the PA’s control path, usuallycaused by parasitics at the OUT pin,
ultimately resultsin the addition of complex poles in the AC loop equa-tion. To avoid
this secondary effect, experimentallydetermine the lowest usable CCLPFfor the power
