RF Power Detector
General Description
The MAX2209 is a wideband (800MHz to 2GHz) RF
power detector. It takes an RF signal from the directional
coupler at the input, and outputs a DC voltage propor-
tional to the RF peak voltage. The change in output
voltage versus temperature is very repeatable from part
to part and enables a lookup table based on nominal
behavior, minimizing the effective detection error to less
than Q0.5dB relative to room temperature.
The MAX2209 comes in a space-saving 2 x 2, 0.5mm
pitch wafer-level package (WLP) and requires only two
external components.

FUNCTION
Detector Output
Power Supply. Bypass to GND with a capacitor as close as possible to the bump.
Ground Connection. Connect to PCB ground plane with as low inductance as possible.
RF Input. Internally terminated to 50I. AC-couple the RF input to this pin.
Detailed Description
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),
cdma2000M, and high-speed downlink/uplink packet
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.
Applications Information
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.

Layout
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 VCC to ground with a capacitor as close as pos-
sible to the part.
