The EMCEE HSDMPowerPlus SeriesTM represents the highest evolution in a high power single conversion multi-channel S-Band transmitter. Inherently low distortion minimizes the need for extensive corrective circuitry and provides for excellent performance in high power analog or digital transmission applications.  A new generation EMCEE designed synthesizer/local oscillator chain provides versatile frequency configuration together with GPS/NAVSTAR or LORAN synchronizing capability for high precision frequency control and co­channel interference reduction in analog operations.  The chassis design incorporates a building block approach for amplifiers and power supplies, providing an eloquent architecture and an inherent soft-fail design approach. A failed amplifier or power supply does not constitute a service outage
