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.
