A Fidelity and Stability Investigation of Solid-State Transceiver Modules.
Abstract
The pulse-to-pulse replication fidelity of solid-state microwave transceiver modules was investigated in terms of performance parameters of an AEW system. The overall distortion introduced by representative state-of-the-art modules was categorized and measured. A first-order time-domain analysis was made, relating nonideal module phase and amplitude response variations which occur as a function of the operating bandwidth to the system time-sidelobe response. Pulse trains consisting of various numbers of contiguous pulses were recorded, and spectral analyses were performed on the recorded data. The measurement apparatus used a carrier-suppression technique to permit obervation of the relatively low levels of module-induced distortion. It was found that the level of distortion introduced by the module was significantly below (some 13 to 16 dB lower than) values which might affect the detection capability of present-day AEW systems.
