Abstract
A time shared power amplifier for amplifying first and second modulated carrier signals for transmission. The carrier signals are modulated by first and second data signals, respectively. The first and second signals are characterized by bursts of data separated by periods of silence. If either of the data signals is presented for transmission while the other is being transmitted, the later one is stored in a storage buffer until the earlier one has been transmitted. Thus, each signal is transmitted during the other's silent periods, and since only one carrier is being transmitted at any given time a much smaller amplifier can be used to amplify the carriers to a given power level than would be required if both carriers had to be transmitted at once.
