18/03/2014 · Now, as would have thought, separate frequency bands are always allocated for uplink and downlink signals, often separated by a gap (maybe for future allocation, since the span of 'guard bands' are relatively very less compared to the actual information-carrying bands, e.g., 100 KHz guard bands in case of GSM-900, where the uplink and downlink bands span 25 MHz each).

The payload of the communications satellite consists of all the components that provide communications services, that is, which receive, process, amplify and retransmit information. The payload can be divided into two distinct parts: the antennas and the repeater. The antennas serve to capture the uplink signal from the earth station and to radiate the downlink signal to other earth …
