PLL frequency synthesizer having a main loop and a secondary loop |
摘要 |
A frequency synthesis system for generating microwaves which includes a main loop with a low gain electronically tunable voltage controlled oscillator (VCO) covering the entire desired frequency bandwidth, and a secondary loop including a direct synthesis section in which frequencies are synthesized directly from a quartz reference which also controls the stability of the oscillator and an indirect synthesis section with a high gain oscillator.
