Specifications of MAX2202EWT+T

Lead Free Status / RoHS Status
Lead free / RoHS Compliant
The MAX2202 RMS power detector is designed to
operate from 800MHz to 2.0GHz. The device is ideal for
wideband code-division multiple access (WCDMA),
cdma2000
access. The device accepts an RF signal at the input
and outputs the same voltage regardless of the peak-
average of the input signal. The output voltage and
input power is linear in dB. The device has a
-29dBm to 0dBm detection range, and every dB
change in input power gives 33mV (typ) change in out-
put voltage.
The device operates from a 2.5V to 4.2V supply and is
specified over the -40°C to +85°C extended tempera-
ture range. The device is available in a 6-bump WLP
package.
