Overview
The ADRF5250BCPZ is a general-purpose, single-pole, five-throw (SP5T) RF switch manufactured by Analog Devices Inc. This device is designed to operate from 100 MHz to 6 GHz and is fabricated using a silicon process. It offers high isolation and low insertion loss, making it suitable for a variety of RF applications. The switch features a 1.8 V logic-compatible, 3-pin control interface and can operate with either a single positive supply voltage or a dual-supply configuration, including an optional internal negative voltage generator (NVG).
