This unit has to be cheap and expendable - it's easy to locate and to destroy by a HARM missile. As a bonus, forcing the adversary to waste a $250,000+ AGM-88 missile on a sub-$100 transmitter may be quite demoralizing.

Microwave ovens were used in the Yugo war for this. The invading air power can't ignore the ISM band because then you could use it for real missile trackers. Someone who can do vacuum and welding work could change the output freq of an oven magnetron, by changing the shorting-strap connections.
