FQ’ Series Q-Circuit Filters
These filters employ the Sinclair-developed Q-circuit design. The operation of the Q-circuit is such that it inverts the characteristics of a standard notch filter, and uses the narrow resonance notch to create the circuit passband while allowing the lower Q elements, such as the loop and its reactance adjustment, to produce the relatively broad isolation notch. The filters can be tuned for either high or low pass condition, with minimum frequency separations. The Q-circuit filter combines the features of a bandpass and reject filter.
