In contrast, indirect phase-. lock-loop (PLL) frequency-synthesis architectures bring smaller-size and lower-cost benefits but. suffer from serious design tradeoffs. Historically, high-performance microwave PLL frequency. synthesizers have relied on YIG-tuned oscillators for broadband operation...

...leveling is the ability to hold power output constant as a function of. frequency. Broad band signal generators usually use Yig Oscillators (By varying dc current to a. Yig Oscillator, the frequency of the oscillator will change as a function of the current input to the. oscillator). To achieve very...
