GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

The ADG901/ADG902 are wideband switches that use a comple-

mentary metal-oxide semiconductor (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. These switches enable the user to pass dc signals up to 0.5 V

without the use of a dc blocking capacitor. 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.
