I like to build simple receivers from 1 to 2.4GHz.
Any recommendations for oscillators?
What schottky diode works to make a signal strength meter?

Thanks

Oscillator construction seems a big problem up there. Was trying something
similar the other week. Turned out 99% art 1% science, so packed it in and
now awaiting a sample of an interesting satelite downconverter chip.
http://www.semiconductors.philips.com/pip/TDA8261.html , digitally covers
950 to 2175MHz using a VCO/synthesiser running at a quarter of it's mixer
input frequency. VCO simply consists of a Varicap, 2 caps and a 18nH
inductor. Chip is 'direct conversion'(with quadrature outputs!) and would
make a wonderful 0-1GHz spectrum analyser if it's mixer ran down to a few
megs. Sadly, no mention of this spec' in the datasheet, so must assume
response tails off badly at the low end.
