AbstractM/A-COM has developed a chip set designed specifically for miniaturized ballistic telemetry applications. One key component of this chip set is a dual port voltage controlled oscillator (VCO). This device allows for independent optimization of both modulation and tuning parameters at the chip level. In the dual port architecture, the modulation port of the VCO may be tailored for the peak (frequency) deviation requirements of each system, while still permitting the device to tune over entire SLOWER band. Additionally, M/A-COM has developed S band power amplifiers (PAs) for medium power (500mW, 1W and 2W) telemetry applications. These new PAs are very efficient, (>45% PAE) when operated in saturation. This improved efficiency means these components may be integrated into transmitters with a miniaturized form factor. The excellent thermal performance of these new PAs allows them to be packaged in commercial plastic packages which are robust in high shock/high vibration applications. This paper reviews the design of each MMIC device and presents system performance data.
