Apr 1, 2015 · Yttrium iron garnet (YIG) tuned oscillators (YTOs) neatly solve this problem with good, wideband phase noise performance and an octave of frequency tuning range but can be large, expensive, and can consume hundreds of mA current due to their tuning currents.

Several versions of this YIG oscillator are available with an external PLL sythesizer for better frequency stability. John Miles, KE5FX, has some excellent documentation and PLL source code on his website at: www.thegleam.com/ke5fx/stellex.htm. It's a little more complicated than the free−running YIG driver shown here.
