Hi,

Try a hairpin loop.

Transmission lines are still quite large at 450MHz and
one less than a quarter-wave will have the inductive
reactance necessary to resonate with your 5pF. The beauty
of them is that you can tap up and down the line quite
easily and variable coupling is a doddle.

Should they work out to be somewhat on the long side for
the board, double them over. Some old ECM transmitters I
came across had what looked like a conventional centre-
tapped tank but which were really rolled up lines.


Cheers - Joe
