Abstract
A system with an acoustic filter array for analog processing of radio signals above 8 GHz includes a receiver and a downconverter to down-convert an incoming signal into an intermediate frequency range (IF). Downconverter includes suppression of local oscillator image. An active manifold splits the IF signal into separate parallel feeds into individual acoustic filter elements in an acoustic filter array. Acoustic filter array provides individually channelized IF outputs. Each IF manifold feed and corresponding acoustic filter output channel is associated with an analog-to-digital converter or system switch.
