DB0805 3dB 90° Test Jigs
GENERAL DESCRIPTION
These jigs are designed for testing the DB0805 3dB 90°
Couplers using a Vector Network Analyzer.
The connectors are SMA type (female), ‘Johnson Components
Inc.’ Product P/N: 142-0701-841.
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.
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.
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
terminal connected to port 2. Follow the VNA’s instruction
manual and use the calibration jig to perform a full 2-port
calibration in the required bandwidths.
Place the coupler on the measurement jig as follows:
Input (Coupler) ꢀ Connector 1 (Jig) Output 1 (Coupler) ꢀ Connector 3 (Jig)
50Ω (Coupler) ꢀ Connector 2 (Jig) Output 2 (Coupler) ꢀ Connector 4 (Jig)
3
To measure R. Loss and I. Loss 1 connect:
Connector 1 (Jig) ꢀ Port 1 (VNA) Connector 3 (Jig) ꢀ Port 2 (VNA)
Connector 2 (Jig) ꢀ 50Ω Connector 4 (Jig) ꢀ 50Ω
To measure R. Loss and I. Loss 2 connect:
Connector 1 (Jig) ꢀ Port 1 (VNA) Connector 3 (Jig) ꢀ 50Ω
Connector 2 (Jig) ꢀ 50Ω
Connector 4 (Jig) ꢀ Port 2 (VNA)
To measure Isolation connect:
Connector 1 (Jig) ꢀ 50Ω
Connector 2 (Jig) ꢀ 50Ω
Connector 3 (Jig) ꢀ Port 1 (VNA)
Connector 4 (Jig) ꢀ Port 2 (VNA)
