RF Transmitters are used to send a radio frequency signal and modulate that signal to carry data from a system. The frequency range is from 315Hz to 64GHz with a data rate of 3kbps to 2Mbps and a power output from -30dBm to 24.7dBm. The data interface is connector, I2C, pads for pins, parallel, PCB, serial, solder pad, SPI, UART, and USB and an antenna connection of castellation, on-board, PCB, and through hole.
