i want to design a vco that works with center frequency 950MHz with no phase noise performance requirements (i don't want to buy it), so what is the value of Q that i should take to have a good (acceptable) performance? the resonator is a 4 element lumped resonator what should be the input/output load resistance?the output is a negative resistance amplifier and the input is a voltage source.when putting the varactor ,should i put it instead of one of the shunt capacitors or in series with it?i am going to use BB149 varactor and i can't calculate its Q because i don't find parallel resistance value Rp in the datasheet.
