High-power Low-pass filter PCB module - It is delivered built & tested as shown in the photo.
It needs 12VDC - 70 mA to operate the relays. The filter is selected when the relays are energized.
If not-energized the input/output port can be routed to another similar PCB module in order to select a different filter.
This way one can use as many filters as he needs.
The selection is done by applying a GND (Ground) to the control input.
The insertion loss and return loss measurements include the two relay contacts.
All capacitors are 2 or 3 KV rated and every filter is measured and tested before shipping.
PCB dimensions: 157.5 x 27 mm
