M/A-COM’s CH20-0032-17G is an IC based monolithic bidirectional coupler in a low cost SOIC-8 plastic package.
This 17 dB coupler is ideally suited for applications
where power monitoring, small size, low insertion loss,
superior repeatability and low cost are required. Typical
applications include base station switching networks,
power monitoring in handhelds and other communication applications where size and PCB real estate is a
premium. Available in tape and reel.
The CH20-0032-17G is fabricated using a passiveintegrated circuit process. The process features full chip
passivation for increased performance and reliability.
