Communications Phased-Array Antenna Module.
Abstract
EQUIPMENT, C band, Hybrid circuits, Microminiaturization, Power amplifiers, Phase shift circuits, Transistor amplifiers, DuplexersA study and investigation was conducted to develop a low-cost receive/transmit module for use in communications phased-array antennas. Design approaches covering the 1 to 8 GHz range were investigated. A module design was recommended for C-band, and key circuits were implemented using hybrid integrated circuit technology. The recommended approach is an all-RF (no conversions to IF) module incorporating a transistor low-noise amplifier in the receive channel and a phase-lock loop stabilized injection-locked oscillator as the power amplifier in the transmit channel. High-Q microstrip design techniques are used to achieve low-loss duplexer filters. Three-bit digital phase shifters are used in each channel to achieve independent transmit and receive beam steering.
