摘要
A multichannel receiver system (10) comprises a first plurality of receiver circuits (12, 14), each having a first input (16, 18) connected to a corresponding one of a second plurality of input lines (20, 22), each being arranged to provide a corresponding one of a third plurality of received signals; a second input (24, 26) connected to a local oscillator (28) arranged to provide a local oscillator signal; and an output (30, 32) arranged to provide a corresponding one of a fourth plurality of output signals (34, 36); and an upconversion mixer (38) having a first mixer input (40) for receiving a reference signal (42); a second mixer input (44) connected to the local oscillator; and a mixer output (46) providing an upconverted reference signal to a fifth plurality of directional couplers (48, 50), each directional coupler connected to a corresponding one of the second plurality of input lines.
