433Mhz transmitter 2

[alerud]

I need to design a 433Mhz transmitter but I have not experience in RF. Does anyone where can I find any circuit?
Does anyone have some circuit for send me?

Why build? You can find off the shelf...

for 433 MHz. <nbucska@pcperipherals.com>

At 433 MHz (a Ham Radio band in North America) there are lots of off-the-shelf parts as well as designs. The last Radio Shack catalog I looked at had a low power 433 MHz data transmitter in it. For a simple single chip solution requiring almost no RF expertise, try RF Monolithics,

-- though they may not have a good way to sell you single pieces if that's what you want.

Can I ask &quot;what are you trying to do&quot;. This band is used in Europe for radio telemetry, and there are many radio modules as well as RS232/RS422/RS485 modems.
