Programmable RF/IF bandpass filter utilizing MEM devices

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.
