ABSTRACT:
An apparatus and method for performing spatial nulling in antenna electronics that provides an integrated solution of signal attenuation and bi-phase modulation. One implementation is comprised of load resistors and field-effect-transistors in a gallium arsenide component configured in such fashion as to provide attenuation and bi-phase capability in response to coupled control signals.
