RF Power Detector

Excellent Accuracy Power-Detector Solution in an Easy-to-Manufacture SC70 Package

Please check latest availability status for a specific part variant.


The MAX2204 RF power detector is designed to operate 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 output 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 package. Electrical performance is guaranteed over a -40°C to +85°C temperature range.
