Filtronic WS004

Filter, Special, Band Reject

(Serial Number 10149 , Stock Number 10149)

Warranty: 30 Days

This is a special purpose filter manufactured by Filtronic to reject a selected frequency in the 6.0 - 12.0GHz (X) pass band. The stop band is a single notch pre-tuned at 8.0GHz, but this would be adjustable if the paint was first removed. There are a number of tuning screws on the filter body. High quality device, quite heavy, probably brass or copper construction. Good cosmetic condition, just a few marks in the paint.

Possible applications for this filter are quite varied, but placed between a radio and antenna it could be used to prevent radiation of the local oscillator signal. This would be useful to reduce spurious emissions from a transmitter or receiver, or perhaps to reduce interference caused by a nearby transmitter? Sorry, no export.
