  2. Amana Corporation - Wikipedia

    en.wikipedia.org/wiki/Amana_Corporation

    Amana was acquired in 1965 by Raytheon, [7] which had invented the microwave oven in 1947, and introduced the commercial Radarange Model 1611 in 1954. [5] In 1967, Amana introduced a consumer model of the Radarange , the first popular microwave designed for home use.

  3. Microwave oven - Wikipedia

    en.wikipedia.org/wiki/Microwave_oven

    A microwave oven or simply microwave is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. [1] This induces polar molecules in the food to rotate and produce thermal energy (heat) in a process known as dielectric heating .

    In 1947, the first commercially produced microwave oven was about 6 feet tall, weighed about 750 lbs, and cost about $5,000 (equivalent to $70,410 in 2024). In 1967 the first more affordable, $495 (equivalent to $4,668 in 2024), and reasonably sized (counter-top) Radarange brand microwave oven was made available for sale, produced by Amana (a ...

  5. Microwave - Wikipedia

    en.wikipedia.org/wiki/Microwave

    A microwave oven passes microwave radiation at a frequency near 2.45 GHz (12 cm) through food, causing dielectric heating primarily by absorption of the energy in water. Microwave ovens became common kitchen appliances in Western countries in the late 1970s, following the development of less expensive cavity magnetrons. Water in the liquid ...

  6. Cavity magnetron - Wikipedia

    en.wikipedia.org/wiki/Cavity_magnetron

    Recent advances in aviation weather-avoidance radar and in marine radar have successfully replaced the magnetron with microwave semiconductor oscillators, which have a narrower output frequency range. These allow a narrower receiver bandwidth to be used, and the higher signal-to-noise ratio in turn allows a lower transmitter power, reducing ...

  7. Waveguide (radio frequency) - Wikipedia

    en.wikipedia.org/wiki/Waveguide_(radio_frequency)

    In radio-frequency engineering and communications engineering, a waveguide is a hollow metal pipe used to carry radio waves. [1] This type of waveguide is used as a transmission line mostly at microwave frequencies, for such purposes as connecting microwave transmitters and receivers to their antennas, in equipment such as microwave ovens, radar sets, satellite communications, and microwave ...
