ABSTRACT:
A dual mode microwave vector controller apparatus is disclosed for controlling amplitude and phase characteristics of RF signals. A first set of phase shifting integrated circuit chips (PSICs) is disposed on a semiconductor substrate, each PSIC having an input port for receiving an RF signal and an output port for transmitting amplitude and phase modulated RF signals. A second set of PSICs is disposed on a semiconductor substrate, each PSIC having an input port for receiving an RF signal and an output port for transmitting amplitude and phase modulated RF signals. A first reciprocal planar magic tee integrated circuit chip (RPMT) is disposed on a semiconductor substrate and sandwichedly coupled between the first and second sets of PSICs, having input ports for receiving RF input signals from one set of PSICs and having output ports for transmitting output RF signals corresponding to the sum and difference of the RF input signals to the other set of PSICs. An electronic controller coupled to each of the first and second set of PSICs for control the extent of phase and amplitude adjustment required for each said RF input signal. A second RPMT chip is disposed on a semiconductor substrate and coupled to the second set of PSICs, with input ports for receiving RF input signals and output ports for transmitting output RF signals corresponding to the sum and difference of the RF input signals.
