CMOS devices makes them ideally suited to wireless and  
general-purpose high frequency switching applications.  
GENERAL DESCRIPTION  
The ADG918/ADG919 are wideband switches using a CMOS  
process to provide high isolation and low insertion loss to  
1 GHz. The ADG918 is an absorptive (matched) switch having  
50 Ω terminated shunt legs, whereas the ADG919 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  
PRODUCT HIGHLIGHTS  
1. –43 dB off isolation @ 1 GHz.  
2. 0.8 dB insertion loss @ 1 GHz.
