GENERAL DESCRIPTION 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 high over the dc to 1 GHz frequency range.
They have on-board CMOS control logic, eliminating the need for external controlling circuitry.
The control inputs are both CMOS and –10 –20 –30 OFF ISOLATION (dB) LVTTL compatible.
The low power consumption of these CMOS devices makes them ideally suited for wireless applications and general-purpose high frequency switching.
