Specifications of MAX2203EWT+T

Lead Free Status / RoHS Status
Lead free / RoHS Compliant
The MAX2203 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 MAX2203 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
-24dBm to +3dBm detection range, and every dB
change in input power gives 35mV (typ) change in out-
put voltage.
The MAX2203 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.
