Microwave injection locking of Magnetrons with beam steering phased
array. Lots of math!

Back in the day, Microwave Associates manufactured a pretty nifty GUNN diode
based FM microwave link for video cameras that operated in the 12-13 GHz band.
The transmitter GUNN oscillator was pumped from a crystal controlled multiplier
chain. At the reciver, an AFC derived from the discriminator kept the link
stable.
Interestingly to time-nutters, since it was FM system, you could insert a
reference at the TX video input and extract it at the RX without any noticible
error. For giggles I connected a G5RV antenna to a TX and a shortwave RX to the
TR and could tune the SW band faithfully.
