Abstract: A radio transmitter having a RF signal source. A splitter receives an input signal from the signal source and divides that input signal into two output signals. Alternatively, two signal generators provide the two output signals. These output signals are fed into two phase shifters. A phase control signal is applied to each phase shifter so that the vector sum of the output signals represents the desired amplitude and phase of the desired transmitted signal. The outputs of both phase shifters are both frequency multiplied and amplified before recombining to form the transmitter output signal. Moreover, the outputs can be transmitted separately and combined at the receiver. Alternatively, in the case of two signal sources, the signal paths may be at different transmitter locations.
