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)  
50Ω (Coupler) ➜ Connector 2 (Jig)  
Output 1 (Coupler) ➜ Connector 3 (Jig)  
Output 2 (Coupler) ➜ Connector 4 (Jig)  
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 3 (Jig) ➜ Port 1 (VNA)  
Connector 4 (Jig) ➜ Port 2 (VNA)  
Connector 2 (Jig) ➜ 50Ω
