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.
The MAX2204 RF power detector converts an RF input signal into a highly repeatable voltage that increases monotonically with input power. It is intended for wideband CDMA, WCDMA, and high‑speed packet‑access applications and features an enable pin for shutdown.
The device operates from a 2.7 V to 3.3 V single‑supply, works over –40 °C to +85 °C, and is offered in a tiny 5‑pin SC70 package. High input impedance allows low‑loss resistive tapping, and external termination enables connection of multiple directional couplers to a single detector chip.
