[amsat-bb] Frequency Doubler?

[Ross Whenmouth]

Hi Bob,

The 1N4005 diode will probably be far to slow for a 451 -> 902 MHz 
doubler as the intended use of the 1N4005 is as a line-frequency 
rectifier. The 1N4148 or 1N914 high speed signal diode should a better 
choice for UHF frequencies.

A full wave rectifier is a good way to produce 2nd harmonic content -
