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 sidebands and inter-modulation products,
¨as a duplexer component.
Design and construction:
The Band-pass Filter consists of 6 high Q resonators.
Filter characteristics:
low insertion loss, high stop band attenuation, steepened filter curve through additional stop poles.
