Hi friends
I want to know whether any of you has designed an oscillator for frequency greater than 20GHz.
Suppose I want to design an oscillator of frequency 20GHz with 1 watt of power.
How to design such oscillator.
I have experience up to only 6GHz & low power oscillator up to 10mW.
Can any one help me regarding.
1) selection of transistor.
2) techniques used for such high power oscillator.
according to my information it is difficuilt to obtain high gain at this frequency.
so standard negative resistance generation ( make s11>>1) method may not work.
please help
Thank you
