Thin-Film Low Pass Filter
LP0805 Test Jig
ITF TEST JIG FOR LOW PASS FILTER 0805
GENERAL DESCRIPTION
These jigs are designed for testing the LPF0805 Low Pass
Filters using a Vector Network Analyzer.
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.
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:
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).
