RF Power Detector
General Description
The MAX2204 RF power detector is designed to oper-
ate from 450MHz to 2.5GHz. The device is ideal for
wideband code-division multiple access (WCDMA),
cdma2000^®, and high-speed downlink/uplink packet
access. The MAX2204 accepts an RF signal at the
input, and outputs a highly repeatable voltage. The out-
put voltage increases monotonically with increasing
input power. The device is designed to compensate for
temperature and process shifts, reducing the typical
output variation to less than ±0.5dB at full input power
and ±1.5dB at the lower power.
The MAX2204 features a detection range from -16dBm
to +5dBm. High input impedance allows for low-loss
resistive tap if an isolator is used. The device uses
external termination at the input so that the RF signal
from several directional couplers can be connected to
a single detector chip.
The MAX2204 operates from a 2.7V to 3.3V power
supply. The device is available in a tiny 5-pin SC70 pack-
age. Electrical performance is guaranteed over a -40°C to
+85°C temperature range.
