Preliminary Report on the Development of a Crystal Controlled L-Band Artillery Telemetry Transmitter,
Abstract
UHF transmitters are extremely sensitive to physical deformation in that such deformation can cause a small change in reactance which can cause an appreciable change in frequency. Since ruggedized crystal-controlled oscillators limit the frequency shift to low levels, they permit early acquisition of artillery telemeter signals; a prototype transmitter was constructed to determine the degree of efficiency and compactness that could be obtained at L-band. A compact 1510-MHZ transmitter having an efficiency of 6 percent at an output power level of 160 mW is described. Physical dimensions are such that the transmitter can be readily potted in any artillery telemetry housing currently in use. Temperature compensation and gun ruggedization tests are currently in progress. (Author)
