The Mini-Kits 400 to 540MHz Butler Oscillator is a modern redesign of the popular butler oscillator design of the early 1990's, and has a number of design changes to improve the oscillator phase noise performance. The oscillator will provide a stable +7dBm output, and is suitable for Transverters and RX Converters from the UHF to Microwave bands. There are optional Kits including a phase locking Kit to allow locking of the oscillator from a stable GSP locked PLL source, and an oven heater Kit to stabilize the temperature.
Standard and High stability Series 5th Overtone Crystals are listed in the Crystal section of the website. Divide your Output frequency by 6 for the required Crystal Frequency.
