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:
“The radio ... goes on early in the morning and is listened to at all hours of the day, until nine, ten and often eleven o’clock in the evening. This is certainly a sign that the grown-ups have infinite patience, but it also means that the power of absorption of their brains is pretty limited, with exceptions, of course—I don’t want to hurt anyone’s feelings. One or two news bulletins would be ample per day! But the old geese, well—I’ve said my piece!”
—Anne Frank (1929–1945)
“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)
