ADG918BRM Datasheet PDF - ADI

GENERAL DESCRIPTION

●The ADG918/ADG919 are wideband switches using a CMOS process to provide high isolation and low insertion loss to 1GHz. The ADG918 is an absorptive switch having 50 ohm terminated shunt legs, while the ADG919 is a reflective switch. These devices are designed such that the isolation is high over the DC to 1GHz 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.
