CL-K59S

Dual Directional Coupler

TECHNICAL BULLETIN

Description

The specifications that are listed should be
considered as "representative" of a family of
directional couplers intended for high power, low
intermod performance, for cellular and PCS use.
The Model CL-K59S was designed for a custom
application in the transmitter path for base station
applications. The frequency range was limited
only by the particular system it was made for;
wider frequency bandwidth's and ranges are
available as may be needed for other
applications.
