ADG904-R - Wideband 37 dB Isolation at 1 GHz CMOS 1.65V to 2.75V 4:1 Mux/SP4T
The ADG904/ADG904-R are wideband analog 4:1multiplexers that use a CMOS process to provide high isolation and low insertion loss to 1 GHz.
The ADG904 is an absorptive/matched mux with 50 Ω terminated shunt legs; the ADG904-R is a reflective mux.
These devices are designed such that the isolation is
