This paper shows how to use the NE602 and NE5212 in VHF andUHF LO generators. The NE602 is a very low power active mixer,yet 7th overtone crystal oscillations are relatively easy to build.Optimization of such circuits is shown in the first part of this paper.Although designed as a fiber optic amplifier, the NE5212 can beused as a feedback oscillator with good results. The second part ofthis paper shows how the NE602 can be used as a frequency doubler.Combinations of the two techniques can give the RF designera wide variety of low power VHF/UHF signal sources from overtoneoscillators and/or frequency multiplier chains.
