Radio electronics is the sub-field of electrical engineering concerning itself with the class of electronic circuits which receive or transmit radio signals.Typically such circuits must operate at radio frequency and power levels, which imposes special constraints on their design. These constraints increase in their importance with higher frequencies. At microwave frequencies, the reactance of signal traces becomes a crucial part of the physical layout of the circuit.
List of radio electronics topics:
- RF oscillator s: PLL, VCO
- Transmitters, Transmission lines, RF connectors,
- Antennas, Antenna theory, List of antenna termsThis is a glossary of antenna-related terms derived from the Glossary of Telecommunication Terms published as Federal Standard 1037C.

- Receivers, TunerA tuner is a device to adjust the resonant frequency of an antenna or transmission line to work most efficiently at one frequency or band of frequencies. A tuner is a radio receiver without an amplifier or loudspeaker, which is often constructed for supers
- AmplifierAn electronic amplifier is a device for increasing the power of a signal. It does this by taking power from a power supply and shaping the output to match the input signal. This process invariably introduces some noise and distortion into the signal, ands
- Modulators, demodulatorA Demodulator is an electronic circuit used to recover the information content from the carrier wave of a signal. The term is usually used in connection with radio receivers, but there are many kinds of demodulators used in many other systems. Another coms, detectorIn telecommunication, the term detector has the following meanings: #A device that is responsive to the presence or absence of a stimulus. In an AM radio receiver, a circuit or device that recovers the signal of interest from the modulated wave. In FM recs
- RF filterAn electronic filter eliminates unwanted frequencies from an electronic signal. There are several kinds of electronic filters: A low-pass filter passes low frequencies. A high-pass filter passes high frequencies. A band-pass filter passes a limited ranges
