An 8-bit 2.5 gigasample A/D converter multichip module for all-digital radar receiver for AN/APS 145 radar on Navy E2-C Airborne Early Warning Aircraft

Abstract

This paper will discuss multichip module (MCM) technology as it is applied to a prototype high performance direct digitizing channelized radar receiver system under development for the Navy's E2-C Airborne Early Warning Aircraft, which encompasses both analog signals at UHF frequencies and multi-gigahertz digital signals. Critical issues which arise in the design of such a system will be discussed, including thermal management, transmission line, voltage standing wave ratio, and simultaneous switching noise analyses. This paper will also describe the various simulation and analysis software tools employed in the development of the MCM containing the analog-to-digital converter (A/D converter) and demultiplexer for this system, and the roles of these tools in providing insight into the design of the MCM.

Implementation of a gallium arsenide multichip digital circuit operating at 500-1000 MHz clock rates using a Si/Cu/SiO/sub 2/ MCM-D technology

“…Examples of such applications are fiber optic transceivers for the communications industry, as well as direct digital synthesizers and A/D converter modules for next generation radar and communications systems [1]. MCM technologies had been described by the early 1980's, and a number of statements were made in the literature as early as 1982 that these tiny structures should create an ideal electrical environment for very high performance digital subsystems and high bandwidth analog systems.…”
