Could I use HMC1165 for 10.9GHz~12GHz?
The frequency range of HMC1165 is 11.07GHz to 11.62GHz.
But in the datasheet HMC1165 supports 10.9GHz~12GHz.
Why your range is narrow compare to performance?
Question: Would it be possible to share the gerber files for the HMC1163 evaluation board?
You need a PLL which drives a frequency doubler which drives an amplifier. Possible choices might be ADF4371 (PLL), HMC1105 (frequency doubler) and HMC7229 (amplifier). These are not the only choices.
