The PIC12LF1840T48A is a Microchip microcontroller
that has an on-board transmitter. The transmitter is
suitable for operation in the 418, 434 and 868 MHz
license-free ISM bands. The modulation is On/Off
Keying (OOK) or Frequency-Shift Keying (FSK). This
document describes the complete implementation of a
radio transmitter using the PIC12LF1840T48A.
