Thin-Film Directional Couplers
DB0805 3dB 90° Test Jigs
GENERAL DESCRIPTION
These jigs are designed for testing the DB0805 3dB 90°
Couplers using a Vector Network Analyzer.
They consist of a dielectric substrate, having 50Ω microstrips
as conducting lines and a bottom ground plane located at a
distance of 0.254mm from the microstrips.
The substrate used is Neltec’s NH9338ST0254C1BC.
MEASUREMENT PROCEDURE
When measuring a component, it can be either soldered or
pressed using a non-metallic stick until all four ports touch
the appropriate pads. Set the VNA to the relevant frequency
band. Connect the VNA using a 10dB attenuator on the jig

The connectors are SMA type (female), ‘Johnson Components
Inc.’ Product P/N: 142-0701-841.
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 50Ω SMA termination.
