Programmable RF/IF bandpass filter utilizing MEM devices

Claim 1

A programmable high frequency bandpass filter for providing a programmed frequency response comprising: an input for receiving an input signal; a micro-electro-mechanical system input capacitor array connected across the input to a ground to provide input matching for the input signal; a plurality of filter sections connected to the input for filtering the input signal and providing a filtered output signal with the programmed frequency response each of said filter sections further comprising: a coupling capacitor array connected in series with the input; and a tuner connected across the coupling capacitor array to the ground for filtering the input signal to provide the filtered output signal with the programmed frequency response; a back end coupling capacitor array connected to a last filter section in the plurality of filter sections for coupling the filtered output signal to an output; a micro-electro-mechanical system output capacitor array connected across the output to the ground to provide output matching for the output signal; and a digital programmable interface for controlling the micro-electro-mechanical system input capacitor array, the coupling capacitor array, the tuner array, the back end coupling capacitor array, and the micro-electro-mechanical system output capacitor array to provide the output signal with the programmed frequency response.
