Band Pass FilterS
Band Pass Filter Micro-2201-C3
Description
Compact band-pass filter Micro-2201-C3 is suitable as receiving or transmitting filter, for one receiving or transmitting channel.
Design and Construction
The band-pass filter consists of 3 high Q resonators
It can be used:
- To improve the input selectivity of receivers and amplifiers
- To increase the isolation of transmitters, whose respective antennas are mounted close together
- To suppress noise saidebands and intermodulation products
Filter Characteristics:
Narrow pass band rang with low insertion loss, high stop band attenuation.
