Power Detector 22GHz to 44GHz
Overview
The WEA2244PD45G is a microwave signal envelope detector. It is capable of detecting signals in the range of -1 dBm to 20 dBm with an accuracy of +/-0.5 dB and produces a voltage proportional to the received signal power. The maximum output voltage is 1.2 V. It consists of 2 parts, the RF part and the Analog processing part that provides a variable gain to extend the detecting range. Multiplexing can also be used to support multiple RF inputs with minimal impact on the silicon area using the same analog part. The Detector is ideal for detecting the envelope of modulated signals in the frequency range from 22 GHz to 44 GHz. The input range can be extended with variable attenuator or amplifier.
