High phase accuracy active phased array module for multi-function radars

Ward, C. J., Forrest, J. R., Malamis, P., Salles, A. A., Brinson, Mike and Parsons, A. J. (1982) High phase accuracy active phased array module for multi-function radars. 1982 IEEE MTT-S International Microwave Symposium Digest. pp. 179-181. ISSN 0149-645X

Abstract

The paper describes an S-Band (2.7-3.1GHz) transmit/receive phased array module giving 40W output for 100µs pulses at 10% duty cycle. The module incorporates closed-loop phase control to reduce to a low level any phase errors between the input reference signal and the output. Initial work on the development of a fibre optic interface for input of the coherent r.f. reference signal is also described.
