Abstract :
A GaAs MMIC gain/frequency conversion chip set and its integration into a module which frequency translates the C/A-coded L1 GPS signals to the 2200-2290 MHz telemetry band for use in tracking artillery projectiles is demonstrated. The custom downconverter, upconverter and power amplifier MMICs which form the transmission chain as well as the 36 cm/sup 3/ module which provides over 125 dB of gain with 3 dB noise figure, survives firing shock of over 8,000 G and operates from 0/spl deg/C to 70/spl deg/C are detailed.<>
