ADL5500 - Analog Devices

ADL5500 100 MHz to 6 GHz TruPwr Detector

The ADL5500 is a mean-responding power detector for use in high frequency receiver and transmitter signal chains from 100 MHz to 6 GHz. It is easy to apply, requiring only a single supply between 2.7 V and 5.5 V and a power supply decoupling capacitor. The input is internally ac-coupled and has a nominal input impedance of 50 Ω. The output is a linear-respon.
