M/A-COM’s CH20-0035-8G is an IC based monolithic bi-
directional coupler in a low cost SOIC-8 plastic package.
This 8 dB coupler is ideally suited for applications where
power monitoring, small size, low insertion loss, superior
repeatability and low cost are required. Typical applica-
tions include base station switching networks, power
monitoring in handhelds and other communication
applications where size and PCB real estate is a premi-
um. Available in tape and reel.
