2. UHF connector - Wikipedia

   en.wikipedia.org/wiki/UHF_connector

   The connector reliably carries signals at frequencies up to 100 MHz. [1] The coupling shell has a ⁠ 5 / 8 ⁠ inch 24 tpi UNEF standard thread. [4] The most popular cable plug and corresponding chassis-mount socket carry the old Signal Corps labels PL-259 (plug #259) and SO-239 (socket #239). [12]

   A double DIN 1.6/5.6 bulkhead jack connector, crimp type, for 75 Ω coaxial cable A Type N connector (male), right-angled solder-type for semi-rigid coaxial cable with a diameter of 0.141-inch. 4.1-9.5 connector, standardized as DIN 47231 (in 1974) and IEC 60169-11 (in 1977) 4.3-10 connector, formerly known as DIN 4.3/10, now standardized as ...

4. Valve RF amplifier - Wikipedia

   en.wikipedia.org/wiki/Valve_RF_amplifier

   A valve RF amplifier (UK and Aus.) or tube amplifier is a device for electrically amplifying the power of an electrical radio frequency signal. Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers during the 1960s and 1970s, initially for receivers and low power stages of ...

5. Valve amplifier - Wikipedia

   en.wikipedia.org/wiki/Valve_amplifier

   A valve amplifier or tube amplifier is a type of electronic amplifier that uses vacuum tubes to increase the amplitude or power of a signal. Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers in the 1960s and 1970s.

6. Motorboating (electronics) - Wikipedia

   en.wikipedia.org/wiki/Motorboating_(electronics)

   In electronics, motorboating is a type of low frequency parasitic oscillation (unwanted cyclic variation of the output voltage) that sometimes occurs in audio and radio equipment and often manifests itself as a sound similar to an idling motorboat engine, a "put-put-put", in audio output from speakers or earphones.

7. 807 (vacuum tube) - Wikipedia

   en.wikipedia.org/wiki/807_(vacuum_tube)

   The 807 also found some use as a horizontal output tube in early TV receivers, particularly those manufactured by DuMont. The 807 design (with some " value engineering " to reduce production cost) was the basis for the first application-specific horizontal sweep tubes such as the 6BG6G and 6CD6G .

8. List of valve amplifier designs - Wikipedia

   The first commercially produced amplifier with distortion of 0.1% was the LEAK Type 15 "Point One" of 1945, using KT66 vacuum tubes (valves) connected as triodes, with 26 dB feedback over 4 stages including the output transformer. In 1948 LEAK produced the TL/12 which was also rated at 0.1% but featured improved performance with 26 dB over 3 ...

9. Feedthrough - Wikipedia

   en.wikipedia.org/wiki/Feedthrough

   A feedthrough is a conductor used to carry a signal through an enclosure or printed circuit board. Like any conductor, it has a small amount of capacitance . A "feedthrough capacitor" has a guaranteed minimum value of shunt capacitance [ clarify ] built in it and is used for bypass purposes in ultra-high-frequency applications. [ 1 ]
