Description

M/A-COM’s CH20-0032-17G 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 base station switching networks,

power monitoring in handhelds and other communica-

tion applications where size and PCB real estate is a

premium. Available in tape and reel.

The CH20-0032-17G is fabricated using a passive-

integrated circuit process. The process features full chip

passivation for increased performance and reliability.

1. All specifications apply with a 50-ohm source and load impedance.
