COMPLEX AMPLITUDE REGULATOR Russian patent published in 1998 - IPC

FIELD: microwave signal processing; adaptive antennas. SUBSTANCE: introduced in device are two quadrature bridges, phase inverter, four-input cophasal adder, and four variable-gain amplifiers interconnected so that first input of first quadrature bridge functions as signal input, matched load is connected to its second input, first output is connected to second input of second quadrature bridge, second output of first quadrature bridge is connected through phase inverter to first input of third quadrature bridge, matched loads are connected to first and second inputs of second and third quadrature bridges, respectively, outputs of second and third quadrature bridges are connected to inputs of amplifiers, respective inputs of cophasal adder are connected to respective amplifier; passband of each amplifier Δf ≥ 1,5Δf_op,, where Δf_op is operating frequency band of adaptive multibeam antenna. EFFECT: eliminated dead zones in phase, improved thermal stability and reduced channel-to-channel error in antenna. 3 dwg
