Hi:
A continuation of the idea of using something other than a square wave
is what Don Lancaster promoted that were called "Magic Sine Waves". The
idea is to come up with a waveform that maximizes the desired output
sine frequency while greatly suppressing the low order harmonics. The

Hi,
As others have already noted, there's a paucity of circuits or down to
earth advice on this topic - unless your poison is "millimetre wave"
technology.
I set out to GPS-lock my Icom 706 transceiver some while ago. This uses
a (single) hi-stability master 30MHz xtal oscillator. With support

Hi
That's the problem.
There's no debate that you can injection lock oscillators. The problem is that
the analytic side of designing an injection lock system is a bit lacking.
With a PLL there's an over abundance of information on how to do the design,
how to analyze it, and how to test it.

Frank,
As Bruce suggests, you can in theory lock any rational number ratio,
including 11/5 and 21/5. However, the locking gain drops off as the
ratio becomes more extreme, and thus the lock range and potential
stability are degraded.
Yes, you could certainly use a regenerative divider to generate
