The low power consumption of these CMOS The ADG936/ADG936-R are wideband analog switches that devices makes them ideally suited for wireless applications and comprise two independently selectable SPDT switches using a general-purpose high frequency switching. CMOS process to provide high isolation and low insertion loss to 1 GHz. The ADG936 is an absorptive/matched dual SPDT PRODUCT HIGHLIGHTS with 50 terminated shunt legs the ADG936-R is a reflective 1. 36 dB off isolation 1 GHz. dual SPDT. These devices are designed such that the isolation is high over the dc to 1 GHz frequency range. They have on-board 2. 0.9 dB insertion loss 1 GHz.
