433mhz schematic

you are right Right, but none of these provide the schematics for 433Mhz/ 300Mhz Rx/Tx Pair


Can anybody provide it ?


Actualy i want to use it with HT12d and HT12e in my brother's final year project

Does anyone have a copy of the RX and TX schematics that used to be at **broken link removed** ?
The RC section of the site does not work anymore.

There is one RX TX circuit:



Translation to English:
Superregenerative 433MHz receiver for remote operation and data transfer. This transmitter and receiver was originally designed as a wireless remote control for example the codec IC HT600 as alarm or car door lock operation but is also suitable for wireless connection between two computers, via the COM port used to about 100 meters.

All inductors 10uH
Antena 2x1cm

DIP to SMD parts :
TL082 TL082CD SO-8
BFY90 BFR93A SOT-23
BF199 BFS20 SOT-23

My PCB 0805 SMD:

it's an old thread, but i'll try... @tpetar: what's the data transfer rate for the last circuit posted? could you post your SMD PCB master? I'll try to use this schema to connect two PIC via RF... thanks!
