摘要：<p>The satellite relay station has its TDMA input signal containing numerous non-overlapping signal pulses each associated with a ground station applied to a distributing circuit (8) whose n outputs are connected via n phase shifters (5) and n power amplifiers (6) to a directional coupler (9). The n outputs from the directional coupler are connected via n multiplexers (2) to the antennae (A) - assigned one to each ground station - for transmission. Signals received by the antennae pass via the multiplexers and n amplifiers (3) to a combining circuit (7) whose single output is frequency shifted (4, 4a, 4b) and passed as TDMA input to the distributing circuit.</p>
