The MAX2209 power detector is designed to oper-
ate from 800MHz to 2.0GHz. The device is ideal for
wideband code-division multiple access (WCDMA),
cdma2000
access. The MAX2209 accepts an RF signal at the input,
and outputs a temperature-independent voltage related
to the input signal voltage. The output voltage expressed
in dBV is proportional to the input power expressed in
dBm. The device has a detection range from -25dBm to
0dBm.
The MAX2209 contains an internal termination resistor
for use with directional couplers. The typical application
circuit is shown in Figure 1. The output of the detector
goes to an ADC for further processing by the baseband
system. Connect a series resistor and shunt capacitor to
the MAX2209 output to reduce residual amplitude ripple.
There are two areas that require attention: the GND pin
and the supply bypassing. Connect the GND pin to the
PCB ground with a GND via as close as possible, and
bypass V
sible to the part.
