Overview
The ADG904BRU-REEL7, produced by Analog Devices Inc., is a wideband analog 4:1 multiplexer designed using a CMOS process. This device is available in two variants: the ADG904, which is an absorptive/matched multiplexer with 50 Ω terminated shunt legs, and the ADG904-R, which is a reflective multiplexer. Both devices offer high isolation and low insertion loss up to 1 GHz, making them suitable for various high-frequency applications.
