Abstract

A multichannel receiver system comprises a first plurality of receiver circuits, each having a first input connected to a corresponding one of a second plurality of input lines, each being arranged to provide a corresponding one of a third plurality of received signals; a second input connected to a local oscillator arranged to provide a local oscillator signal; and an output arranged to provide a corresponding one of a fourth plurality of output signals; and an upconversion mixer having a first mixer input for receiving a reference signal; a second mixer input connected to the local oscillator; and a mixer output providing an upconverted reference signal to a fifth plurality of directional couplers, each directional coupler connected to a corresponding one of the second plurality of input lines.
