Title: IF bandpass filter circuit with resonant reactance network - capacitively coupled between input and output resonant circuits and generating single attenuation pole
IPC: H03H7/01
Filed: 1972-02-18
Granted: 1984-03-01
Abstract: The IF bandpass filter circuit has an input and an output resonant circuit coupled together and with a reactance network between them. The reactance network consists of a resonant circuit coupled via series capacitors to the secondary side of the input resonant circuit and to the primary side of the output resonant circuit. Two capacitors connect the reactance network to a reference potential. The reactance network generates an attenuation pole at a frequency equal to the resonant frequency of its resonant circuit such that the frequency response of attenuation and group transit time in the pass-band is arithmetically symmetrical about the centre frequency. The advantage lies in high selectivity.
