... 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 reflective dual SPDT. These devices are designed such that the isolation is high over the GHz frequency range. They have on-board CMOS control logic, eliminating the need for external controlling circuitry ...
