ever since someone here (audioguru?) mentioned the use of a varicap,
I have a question.
what is the best diode to use as a varicap?
I am using a 6V - 9V DC power supply. Sometimes battery, sometimes, a DC adapter. The frequency I am dealing with is between 100 and 200Mhz.
and I want the varicap to have at least a 1pF range.
I looked at the 1N914's and the datasheet shows that I can go as far as 0.2pF at 1Mhz.
Is a 1N914B suitable?
I also have a 1N4007 which I think is unsuitable.
I don't know.
