What do you mean by simple receivers ? What are you trying to receive,
with what stability and sensitivity ? Amateurs have traditionally used
crystal-controlled downconverters in front of lower frequency
receivers, but this is generally suited only for receiving small
segments of spectrum and doesn't usually have a very small parts count.
The local oscillator usually involves several multiplier stages and
tunable filters. The performance can be very good though.

Something that can be built with 1 chip just to experiment for now.
From what I read, regular fiberglass boards don't work well above 1 GHz.
Where do you get teflon boards?
