I don't know if there is anything in my handbook on frac-N synthesisers. No doubt I will find it on the net.
The Fast tuning Slow Huff & Puff uses either a 64 to 128 stage shift register to create long or short delays in vco responce as well as has the main IC able to adjust the step rate. Thermal stabilization via a tunable circuit from the Hand Book seems to be the way to add extra stablility to the H&P circuit. So far there are numerous spin off circuits of the Huff & Puff and now they are studying the jitter and phase noise aspects and seem to be on top of it all. I am sure that here soon we will start to see some ideas towards a full blown receiver circuit for home brew. I know I plan to work on these ideas as soon as I get my mail order parts in. Fractal-N synthesis seem like something to look into since it was mentioned that it is being looked into for microwave uses. I realize that technology for microwave has to be very frequency stable for a starter. I ordered some PLL chips from Texas Instruments to explore what can be done with them as I study H&P ideas. They are fairly cheap. .48 cents there about. _____________________________________________________________________ Call Anyone, Anytime, Anywhere in the World - FREE!
