In case any purists want to scoff at this matching technique and think it is a bodge, I suggest they take a look inside a typical HP power meter and look at how the 1mW oscillator is designed and how it achieves its output match. It uses a tiny series inductor to cancel out the capacitance of the capacitive divider used at the output of the oscillator. This ideally leaves a pure (series) 50 ohm source impedance at 50 MHz. This is how HP tried to get a very low source VSWR for their 1mW source at 50 MHz.

Obviously, it's a good idea to try and trim the tiny inductance to be spot on and that is what I have done here in order to get a really low VSWR at 50 MHz.

If it's good enough for HP then it's good enough for me :)
