Balanced SAW Filter MeasurementHow to measure Balanced SAW Filters

1: Before measurement You should calibrate every measuring port of Net Work Analyzer (Port1, Port2). If the way of calibration is not right, measured data should be different from correct one. Electrical delay of test fixture (measurement jig) should be set by port extension of NWA.

For Example Port 1 Port 2 Filter Port 1 80ps Filter Port 2 95ps Filter Port 3 95ps

Murata uses Electric calibration module (E-cal) as calibration kit. But you can use 3.5mmD hand calibration kit, too. If you calibrate accurately, the result measured by NWA should be the same. Before measuring the samples, you should not forget to set Electrical Delay (Port Extension) by NWA. To set Electrical Delay by NWA, you should connect test fixture to the cable of NWA after calibrati
