Hybrid Couplers 3dB, 90º
Type PC2025A2100AT00
HYBRID COUPLER TEST JIGS
GENERAL DESCRIPTION
These jigs are designed for testing the 3dB Hybrid Couplers
using a Vector Network Analyzer. They consist of a dielectric
substrate, having Cu microstrips as conducting lines and a
bottom ground plane located at a distance of 0.254mm from
the microstrips.
PIN: l42-070l-84l. Both a measurement jig and a calibration
jig are provided. The calibration jig is designed for a full 2-
port calibration, and consists of an open line, short line and
through line. LOAD calibration can be done by a 502 SMA
termination.
The substrate used is Taconic RF 35 0100. The connectors
are SMA type (female), ‘Johnson Components Inc.’ Product
MOUNTING AND MEASUREMENT PROCEDURE
PIN CONFIGURATION
The PC2025A2100 part has an orientation marker to denote
Pin 1. Once port one is determined the other ports are
As defined; See the chart below for clarification:
MLO™ hybrid couplers require a 50Ω transmission lines
leading to and from all of the RF ports. Proper grounding is
required in order to ensure optimal device performance.
All of the MLO™ components utilize castellated intercon-
nects which allow for high yield assembly, expansion
matched and halogen free dielectrics.

The MLO™ hybrid coupler is a symmetrical device. When a
port is designated as the input, automatically the two output
and isolated ports are defined. For example, if the input port
for a device was selected to be Pin 1, Pin 2 is automatically
the isolated port, Pin 4 is the 0 degree reference output
port, and Pin 3 is the output port which “lags” behind the
reference output port by 90 degrees. Similarly, if Pin 3 was
to be selected as the input port, the adjacent port on the
long side (Pin 4) is the isolated port, the adjacent port on
the short side (Pin 2) is the 0 degree output port, and the
opposite port (Pin 1) is the 90 degree output port.
