Can mmic oscillators be used in push-push topology?

I have doubds. Mainly because resonant network is inside oscillator, but maybe there something i do not know..

nope
push push means the devices are working at half the frequency of the actual output.

if u just randomly hook up two oscillator chips, one will injection lock to the other and the devices will be running at the output frequency, not half of it.
