Maxim introduced the MAX1479 , the world's smallest VHF/UHF PLL-based ASK/FSK transmitter to deliver more than +10dBm output. It is housed in a small, 3 x 3mm, 16-pin thin QFN package. The transmitter ...

In that case, [Electronoobs] has an Arduino powered RC transmitter with your name on it. But this is no scrap of protoboard with a couple of cheap joysticks on it, though he has made one of those too.

Long-range RC transmitter “I started using Bluetooth devices like the HC-05 modules, but I found that these sometimes randomly disconnected.

The UHF ASK/FSK PLL transmitter ICs ATA8401 (310 – 350 MHz), ATA8402 (423 – 439 MHz), and ATA8403 (868 – 928 MHz) are designed for low-cost RF transmission systems in industrial and consumer ...

The MAX7057 crystal-referenced ASK/FSK transmitter can operate at any frequency in the 300 MHz to 450 MHz range with the proper crystal frequency and can transmit data at rates up to 100 kb/s NRZ ...
