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.
