Abstract

1,137,139. Filter networks. A. C. COSSOR Ltd. 17 Aug., 1966 [10 Sept., 1965], No. 38800/65. Heading H3U. A band-pass filter comprises two parallelresonant circuits having the same resonance frequency coupled together by means of a capacitor having a resistor in series or in parallel therewith, there being no electromagnetic coupling between the inductors of the two resonant circuits. The filter is intended for use as a matching network between an L-band mixer and an I.F. amplifier and serving to remove frequency-dependent variations in signal level.
