宽带2.5 GHz的37 dB的隔离在1 GHz ， CMOS 1.65V至2.75V ， 4 ： 1多路复用器/ SP4T Wideband 2.5 GHz, 37 dB Isolation at 1 GHz, CMOS 1.65V to 2.75V, 4:1 Mux/SP4T
GENERAL DESCRIPTION
The ADG904 and ADG904-R are wideband analog 4:1 multiplexers 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 high over the dc to 1 GHz frequency range.
