There were some issues with the tested version 1.0. It seems that desire to go cheap backslashed at me. I hoped I'll be able to go with 2-layered board with this oscillator. But unfortunatelly, it didn't work as planned. There was long return trace due to the ground plane not being even on any of two layers. 

Microwavino v2.0 consists of 4 layers what should eliminate these issues and make everything work as in my project microwave transmitter.
