Overview
The ADG902BRMZ is a wideband RF switch IC produced by Analog Devices Inc. It utilizes a complementary metal-oxide semiconductor (CMOS) process to offer high isolation and low insertion loss up to 1 GHz. This device is particularly suited for wireless communications, general-purpose RF switching, and various high-frequency applications. The ADG902 is a reflective switch, contrasting with the ADG901 which is an absorptive switch. Both devices are designed to provide high performance with minimal power consumption, making them ideal for battery-powered and energy-efficient systems.
