GENERAL DESCRIPTION

The ADG901/ADG902 are wideband switches that use a CMOS process to provide high isolation and low insertion loss to 1 GHz. The ADG901 is an absorptive (matched) switch with 50 Ω terminated shunt legs, while the ADG902 is a reflective switch. 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, thus eliminating the need for external controlling circuitry. The control inputs are both CMOS and LVTTL compatible. The low power consumption of these CMOS devices makes them ideally suited to wireless applications and general-purpose high frequency switching.
