ABSTRACT:
An RF circuit includes an RF power divider circuit having an input port and a plurality of output ports the RF power divider circuit providing in response to a signal fed to the input port an output signal at each output port each output signal having known amplitude and known phase. The RF circuit further includes means for selectively coupling at least a portion of a signal fed to an input port of the RF circuit to the input port of the RF power divider circuit and a like plurality of directional coupler circuits each of the coupler circuits having an input port and a coupled port with each input port coupled to a corresponding one of the plurality of output ports of the power divider circuit and each coupled port corresponding to an output port of the RF circuit.
