Abstract
A transceiver receives linearly polarized signals from two geostationary satellites. The transceiver includes a first and second waveguide to form two receiving beam patterns with a maximum gain in angular directions different from each other. At one end of each waveguide, two receiving elements orthogonal to each other are provided. Four converting units convert, using a common local oscillator, the carrier frequency of the four signal components received from the two pairs of receiving elements into an intermediate frequency. A combining unit linearly combines the converted signal components, based on weights representing phase shifting and/or amplification of signal components. A weight input unit receives the weights to be used in the combining unit.
