Abstract
Large-aperture phased array antennas are designed with fiber-optic (FO) distribution networks to provide phase and frequency reference signals, control signals for beamsteering and beamshaping, and data/frequency hopping signals to MMIC active transmit/receive modules. The experimental results of an FO communication network at the mm-wave frequency of 38 GHz (Ka band) are presented. The results of 500 MHz to 1 GHz FO link characteristics such as frequency response flatness, harmonics, and third-order intermodulation distortion are presented. Results of stabilization of a 38 GHz IMPATT oscillator using indirect optical injection locking is also discussed. A locking range of 132 MHz using 45 dB amplification gain is demonstrated. The overall system FM noise degradation is measured to be 16 dB. The communication link is established by upconversion of the data link with the stabilized LO. Results of a true time delay phase shifter using a novel fiber-stretching technique is presented. A phase shift as high as 20 deg at 10 GHz is achieved using the expansion properties of a piezoelectric ring excited by a dc voltage. (Author)
