ORION downconverter and power supply
Abstract
The receiver subsystem supplies the front end assembly (downconverter) and power supply for the ORION Mobile Station. These assemblies are designed to withstand severe environmental conditions. The mechanical, electronic, environmental and maintenance design considerations encountered during the design phase of this project are discussed. The two channel S/X downconverter has a 400 MHz bandwidth channel. Phase stability of 2 and 7 deg at S- and X-bands, respectively, is achieved with a temperature stabilized first local oscillator.
