COLLINS FR4QX22YY 200Hz-3kHz / # T W2D 9560

Description

Welcome
at company auctions
PatKor Shop
In this auction we offer:
I offer you a low-frequency filter from the well-known American company Collins.
The filter was intended for use in radio communication equipment.
It is a filter made on LC circuits so it does not introduce additional interference or noise to the signal.
It is perfect for receiving devices because it excellently cuts out all noise at higher frequencies. This is important as current high frequency amplifiers have bands in the order of 10kHz.
The filter was used in military equipment, so it is adapted to difficult working conditions.
It was made very solidly.
The filter has two symmetrical inputs.
The filter attenuation in the passband is about -15dB
The rejection in the stop band is about -50dB
The filter is in a very good condition, some pieces may have delicate paint chips.
The diagram of the filter leads is printed on its housing.
