1. A phase and amplitude modulator comprising:

  • means for generating a plurality of phases from an input signal;

    means for separately amplifying each of the generated phases, which means may be modulated to change the amplitude output of each phase in response to a modulating signal, wherein said means for amplifying comprises field effect transistors in push-pull configuration; and

    ,means for summing the output of the said amplifying means such that a single output signal of modified phase and amplitude is obtained.
