PLL Frequency Synthesis in On-Board Satellite L-Band Front-End
Original language 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 ratedata 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 inventiion 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.

Kmitočtová syntéza PLL v palubním družicovém vstupním dílu pro pásmo L
Czech description
V článku je popsán nový způsob generace signálů mísních oscilátorů v palubním přijímači pro pásmo L. Signály jsou generovány dvojitým kmitočtovým syntezátorem s nízkým šumem zejméne v blízkosti nosné, což je vyžadováno pro přenos pomalých dat PSK modulacemi.
