Radio frequency, or RF, is a carrier, or alternating current with or without a signal, at a frequency that can radiate, or propagate, if not shielded. Such frequencies account for the following parts of the electromagnetic spectrum:
- Very low frequency (VLF): 3-30 kHz
- Low frequency (LF): 30-300 kHz
- Medium frequency (MF): 300-3000 kHz
- High frequency (HF): 3-30 MHz
- Very high frequency (VHF): 30-300 MHz
- Ultra high frequency (UHF): 300-3000 MHz
- Super high frequency (SHF): 3-30 GHz
- Extremely high frequency (EHF): 30-300 GHz
Analog signals that are not RF include IF (intermediate frequency) and AF (audio frequency, 20-20000 Hz).
Electrical connectors designed to work at radio frequencies are known as RF connectors. RF is also the name of a standard audio/video connector, also called BNC (BayoNet Connector).
