TEST JIG FOR LP0402 LOW PASS FILTER

GENERAL DESCRIPTION

These jigs are designed for testing the LP0603 LGA Low Pass Industrial filters using a Vector Network analyzer.

They consist of a dielectric substrate, having 50Q microstrips as conducting lines and a bottom ground plane located at a distance of 0.127mm from the microstrips.

The substrate used is Neltec's NH9338ST0127C1BC (or similar).

The suppliers of 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 50Q SMA termination.

MEASUREMENT PROCEDURE

Follow the VNA's Instruction manual and use the calibration jig to perform a full 2-Port calibration in the required band-widths.

Solder the filter to the measurement jig as follows:

'^nput Connector 1 (Jig) (Filter) ^v ^M;

0_^utput ^ connector 2 (Jig)

GND (Filter) GND (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).
