Thin-Film Directional Couplers
CP0805 and CP0603 Test Jig
GENERAL DESCRIPTION
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.
MEASUREMENT PROCEDURE
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).
