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