DESIGN OF RF DOWN CONVERTER FOR IRNSS USER RECEIVER

Abstract

 This paper demonstrates the design of RF front end down converter for IRNSS user receiver. Here the IRNSS frequency L5 (1176.45 MHz), S1 (2492.028 MHz) and GPS (1575.42 MHz) are down converted to a common Intermediate frequency (IF) 72.221 MHz. The Down Converter proposed here is interfaced between the antenna and Base Band Card, for down converting and pre-conditioning the Radio-Frequency signal. A prototype of the design is successfully used in finding the user position with an accuracy of 0.5 meter.
