They consist of a dielectric substrate, having 50W microstrips as conducting lines and a bottom ground plane located at a distance of 0.254 mm from the microstrips. The substrate used is RF-35-0100-C1B107 (or similar). The connectors are SMA type (female), ‘Johnson Components Inc.’ Product P/N: 142-0701-841(or similar). 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 50W SMA termination. Follow the VNA’s instruction manual and use the calibration jig to perform a full 2-Port calibration in the required bandwidths. Solder the filter to the measurement jig as follows: Input Connector 1 (Jig) GND (Filter) GND (Jig) (Filter) Output Connector 2 (Jig) GND (Filter) GND (Jig) (Filter) Set the VNA to the relevant frequency band. Connect the VNA using a 10dB attenuator on the jig terminal connected to port 2 (using an RF cable).
