Concept Study for UHF T/R Modules
Abstract
This report discusses some important issues related to the performance and producibility of ultrahigh frequency (UHF) transmit/receive modules. Unfortunately, there are a number of factors which currently limit precision phase and gain tracking between such modules. Some of this variability results from imperfections in the modules themselves while other contributors are a consequence of the very nature of the array environment. An analysis of these issues, with a concomitant identification of the major gaps in the knowledge base of underlying technologies, permits the development of an 'investment strategy' for UHF. Some pillars of this strategy involve the use of transistors at lower frequencies, a re-visiting of balanced circuitry, the development of both improved power devices and methods to power combine such devices, an optimization in the level of integration and the incorporation of post-assembly tweaking techniques for module manufacturing. Augmenting these activities with enhancements in both open-loop and closed-loop module control help permit the deployment of phased array radars with performance envelopes will beyond the current state-of-the-art.
