Abstract :
A 4-bit instantaneous frequency measurement (IFM) subsystem operating in the 1.5–4.66 GHz frequency band has been developed based on multi-band-stop filters. The design instantaneously detects the incoming signal which is then associated to one of the 16 sub-bands. Design, simulation and measurement of the device are presented in this paper, where a good agreement between simulations and measurements was obtained.
