Hi , Every Body
Happy New Year

Do You Know How Can I Build SuperRegenarative Receiver for UHF 433 MHz (carrier)
Band Which i want to use this Receiver for 10 Mbps FSK Reception Circuit?

Is it Possible to send Both 435 MHz (Stands for Mark) and 437 MHz (Stands for space) In Transmitter And Make a SuperReg Receiver to take Mark and Space
By Multiply 435MHz (received signal)*433 (MHz) and taking 2 MHz Mixed Signal for
Mark and 4MHZ Signal for Space.If It's Possible Please Explain.

And if we want to use Crystal Filter For this purpose Which XTAL and How we should design that ?

Plz Help me if You know any usefull Articles about Crystall Filters and SuperRegenarative Receiver .

Best Regards
 

You are going to have several problems with this concept. This type of receiver is sampling. The quench frequency will have to be several times the bit rate. This will not leave many RF cycles for the regeneration to build up or go down.

Try a tuned RF type (chain of amplifiers on your operating frequency) and a transmission line type delay and multiply FM detector.

There is also the legal limit of power and bandwidth you can use. I suspect that you are exceeding both in your system needs.
