ITF TECHNOLOGY
The ITF High Directivity Wide Band LGA Coupler is based on thin-
film multilayer technology. The technology provides a miniature
part with excellent high frequency performance and rugged
construction for reliable automatic assembly.
The Wide Band High Directivity Coupler displays a stable coupling
factor over a wide frequency band.
QUALITY INSPECTION
Finished parts are 100% tested for electrical
parameters and visual characteristics. Each
production lot is evaluated on a sample basis for:
• Static Humidity: 85°C, 85% RH, 160 hours
• Endurance: 125°C, IR, 4 hours
TERMINATION
Nickel/Lead Free solder coating compatible with
automatic soldering technologies: reflow, wave
soldering, vapor phase and manual.

GENERAL DESCRIPTION
These jigs are designed for testing the CP0402W2700FNTR
High Directivity 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 (0.010") from the microstrips.
The substrate used is Neltec’s NH9338ST0254C1BC.
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.
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:
GND (Coupler) Connector 1 (Jig) IN (Coupler) Connector 3 (Jig)
Coupling (Coupler) Connector 2 (Jig) Out (Coupler) Connector 4 (Jig)
To measure I. Loss connect:
Connector 3 (Jig) Port 1 (VNA) Connector 2 (Jig) 50Ω
Connector 4 (Jig) Port 2 (VNA)
To measure R. Loss and Coupling connect:
Connector 3 (Jig) Port 1 (VNA) Connector 4 (Jig) 50Ω
Connector 2 (Jig) Port 2 (VNA)
To measure Isolation connect:
Connector 4 (Jig) Port 1 (VNA) Connector 2 (Jig) Port 2 (VNA)
Connector 3 (Jig) 50Ω
