ADG936-R - Analog Devices

ADG936-R Wideband 4 GHz 36 dB Isolation at 1 GHz CMOS 1.65V to 2.75V Dual SPDT

The ADG936/ADG936-R are wideband analog switches that comprise two independently selectable SPDT switches using a CMOS process to provide high isolation and low insertion loss to 1 GHz. The ADG936 is an absorptive/matched dual SPDT with 50 Ω terminated shunt legs; the ADG936-R is a reflective dual SPDT. These devices are designed such that the isolation is h.
