ads vco example

At 7 GHz, you might use a transmission line as a resonator. I have done an osc at 5 GHz using a transmission line on Roger substate. It works fine. I have nerver tried at 7 GHz. You might also tried to use dielectric resonator. ADS has a model for it

ads tutorial vco

You can use MOS technology files and convert them in ADS for your simulation. For example 0.18um or 0.13um
