Thin-Film Directional Couplers
CP0805 Type
GENERAL DESCRIPTION
ITF (Integrated Thin-Film)
TECHNOLOGY
The ITF SMD Coupler is based on thin-film multilayer technol-
ogy. The technology provides a miniature part with excellent
high frequency performance and rugged construction for
reliable automatic assembly.
The ITF Coupler is offered in a variety frequency bands com-
patible with various types of high frequency wireless systems.

Thin-Film Directional Couplers
Test Jig
ITF TEST JIG FOR COUPLER 0805 AND 0603
GENERAL DESCRIPTION
MEASUREMENT PROCEDURE
This jig is designed for the testing of CP0805 and CP0603
series Directional Couplers using a vector network analyzer.
It consists of a FR4 multi-layer substrate, having 50Ω
microstrips as conducting lines and a ground plane in the
middle layer, located at a distance of 0.2mm from the
microstrips.
The connectors are SMA type (female), ‘Johnson Components
Inc.’ Product P/N: 142-0701-881.
The jig is designed for a full 2-port calibration. LOAD calibration
can be done either by a 50Ω SMA termination, or by soldering
a 50Ω chip resistor at the 50Ω ports.

When measuring a component, it can be either soldered or
pressed by a non-metallic stick until all four ports touch the
appropriate pads. To measure the coupling (and the R. Loss)
place the component on the Port 1 & Port 2 pads. Use two
SMA 50Ω terminations (male) to terminate the ports, which
are not connected to the network analyzer, and connect
the network analyzer to the two ports. A 90° rotation of
the component on its pads allows measuring a second
parameter (I. Loss).
