A magnetron is a high-power, high frequency vacuum tube.

The magnetron is the source of radio-frequency energy in RADAR systems

and in the microwave oven in your kitchen, for example.

A transmitter sends a radio frequency to a robot.

1. AM radio broadcasting uses frequency division multiplexing to allocate different frequencies to different radio stations.
2. Cable television systems use frequency division multiplexing to transmit multiple channels simultaneously over a single cable.
3. Cell phone networks use frequency division multiplexing to separate different users' calls on the same frequency band.

Single Channel Ground Air Radio Systems (sincgars) can operate in VHF (very high frequency) low band 30.0000 MHz to 89.9999 MHz or VHF high band which is 90.0000 MHz to 224.9999 MHz
