Hi
I am trying to do some simulation on the cuicut below which is used in speed measuring radar.
After the power up, the oscilator works and transmits 2.4GHz(maybe) signal, after hits some moving object, the return signal mix with the orignal signal in the mixer,and a low frequency can be got, so the speed can be calculated.
the transistor may be 2sc3585 or 2SC4228
But when I simulate with ADS, the oscilation can not be got.

could you help me to solve this problem
