Technical content

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, I R, 4 hours TERMINATION Nickel/Lead Free solder coating compatible with automatic soldering technologies: reflow, wave soldering, vapor phase and manual.

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.
