Overview
The ADG919BRMZ-REEL7, produced by Analog Devices Inc., is a wideband RF switch designed using a CMOS process. This component is part of the ADG918/ADG919 series, which offers high isolation and low insertion loss up to 1 GHz. The ADG919 is specifically a reflective switch, distinguishing it from the absorptive switch ADG918. These switches are optimized for various RF applications, including wireless communications, general-purpose RF switching, and antenna diversity switching.
