Patent ID: 7058377

Claim:
A dual channel downconverter comprising: a two-channel heterodyne receiver architecture, said two-channel heterodyne receiver architecture comprising separate and distinct first and second downconverting signal channels; wherein said second downconverting signal channel comprises; first and second RF signal input ports; a first power divider electrically connected to said first RF signal input port; a first amplifier electrically connected to said first power divider; a first mixer network electrically connected to said first amplifier; a fixed-frequency IF clock electrically connected to said first mixer network; a second amplifier electrically connected to said first mixer network; a second power divider electrically connected to said second amplifier; a second mixer network electrically connected to said second RF signal input port and said second power divider; and a second IF signal output port electrically connected to said second mixer network; wherein first and second frequency-agile, pulsed RF input signals are downconverted to, respectively, first and second fixed IF output signals without use of a tunable local oscillator.
