Description

M/A-COM’s CH20-0033-17G is an IC based monolithic bi-directional 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 personal communication systems and other communication applications where size and PCB real estate is a premium. Available in tape and reel. The CH20-0033-17G is fabricated using a passive- integrated circuit process. The process features full chip passivation for increased performance and reliability. 1.
