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, Voltage-controlled oscillator
- 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
Famous quotes containing the words radio and/or electronics:
“Now they can do the radio in so many languages that nobody any longer dreams of a single language, and there should not any longer be dreams of conquest because the globe is all one, anybody can hear everything and everybody can hear the same thing, so what is the use of conquering.”
—Gertrude Stein (1874–1946)
“We live in a highly industrialized society and every member of the Black nation must be as academically and technologically developed as possible. To wage a revolution, we need competent teachers, doctors, nurses, electronics experts, chemists, biologists, physicists, political scientists, and so on and so forth. Black women sitting at home reading bedtime stories to their children are just not going to make it.”
—Frances Beale, African American feminist and civil rights activist. The Black Woman, ch. 14 (1970)
