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 oscillators: PLL, VCO
• Transmitters, Transmission lines, RF connectors,
• Antennas, Antenna theory, List of antenna terms
• Receivers, Tuners
• Amplifiers
• Modulators, demodulators, detectors
• RF filters
• RF shielding, Ground plane
• PCB layout guidelines
• DSSS, Noise power
• Digital radio
