Abstract :
1.5 GHz module for the phase/amplitude processing is considered. The new principle of operation based on the combination of digital and analog regimes for different cascades of module allows to increase the figure of merit of device and to provide the effectively suppression of phase and amplitude errors. Device is based on GaAs hyperabrupt tuning varactors and consists of 360° digital-analog phase shifter with figure of merit F=240 deg/dB in 13% bandwidth and (0.25÷4) dB tunable attenuator, which are integrated in one module using the printed circuit board (PCB) technology. Possibility to improve the device parameters due to the use of LTCC technology considered also.
