Abstract
A tunable vector recombination amplifier comprises an input, an output, first and second amplifier circuit paths each including a respective phase shifter to receive a respective input signal from the input and to apply a respective phase shift to produce a respective phase-shifted signal, a respective interstage impedance matching network, and a respective amplifier connected between the respective phase shifter and interstage impedance matching network to receive and amplify the respective phase-shifted signal to produce a respective amplified signal, first and second controllable DC voltage sources each coupled to a respective amplifier and configured to provide a respective supply voltage to the respective amplifier, values of the supply voltages being independently controllable, and an output amplifier stage to receive, amplify, and vectorially combine the amplified signals to produce a combined signal having a specified phase determined by the phase shifts and supply-voltage values and a specified amplitude at the output.
