dcterms:description
The new conception of local oscillators signals generation in a L-band front-end is presented. The front-end is designed as a part of the new AMSAT Phase 3E satellite. High reliability and low power consumption of the receiver is required. For slow rate data transmissions as telemetry PSK, high stable local oscillators in the double conversion receiver are required and retuning of the first oscillator is asked. Conventional solution uses a stable quartz oscillator with frequency multipliers. The invention of the receiver design consists in replacement of frequency multipliers by the double PLL synthesizer synchronized by an ultra stable oscillator positioned on-board the satellite.
