Radios are communication systems that send and/or receive electromagnetic waves.

Wireless modems transmit modulated data using electromagnetic waves.

Terrestrial and satellite radio service providers transmit radio programming over satellite, cable networks and over open airwaves

Radio modems are radio frequency transceivers for serial data.

Antennas are structures or devices used to collect or radiate electromagnetic waves.

Radio Receiver ICs support worldwide radio band requirements, including FM, FM radio data system (RDS), AM, long wave (LW), short wave (SW) and weather bands on a chip

RF filters and microwave filters are devices that pass or reject signals by frequency.
