Maxim Integrated MAX2209 RF Power Detector
Maxim Integrated MAX2209 RF Power Detector is the industry's smallest power-detection circuit. This Maxim Integrated wideband (800MHz to 2GHz) RF power detector takes an RF signal from the directional coupler at the input and then outputs a DC voltage proportional to the RF peak voltage. The MAX2209 features a -25dBm to 0dBm power detection range and minimizes effective detection error to less than ±0.5dB relative to room temperature. This Maxim Integrated RF power detector is ideal for use in a variety of applications, including dual-band WCDMA handsets, High-Speed Downlink Packet Access (HSDPA), and High-Speed Uplink Packet Access (HSUPA).
