A TWTA consists of a traveling-wave tube coupled with its protection circuits (as in klystron) and regulated power supply electronic power conditioner (EPC), which may be supplied and integrated by a different manufacturer. The main difference between most power supplies and those for vacuum tubes is that efficient vacuum tubes have depressed ...
Stellant is known for their traveling-wave tubes (TWTs), traveling-wave tube amplifiers (TWTAs), microwave power modules (MPMs) and electronic power conditioners (EPCs) as well as xenon gas ion propulsion systems (XIPS). [1] Since its inception, EDD has produced tens of thousands of TWTs. [2] They are the only U.S. supplier of space-qualified ...
Microwave tubes: Frequency in GHz; Rectifying tubes: DC output voltage in kV; Thyratrons: Peak inverse voltage in kV; Transmitting tubes: Maximum anode voltage in kV; The following group of digits indicate the power: Backward-wave amplifier or Traveling-wave tube: Output power; 2nd letter: A – in mW; 2nd letter: B – in W; Klystrons: Output ...
In 1959 Bob Coulson established travelling-wave tube and microwave tube sections, and they were producing ceramic hydrogen thyratrons as well. By this time EEV was the largest hi-tech manufacturing company in the UK. A year later they won an EMMY award for
These are supplied by TESAT to satellite manufacturers worldwide. Among the equipment and systems manufactured for satellite telecommunications are high-power amplifiers such as traveling wave tube amplifiers (TWTA) and their power supplies electronic power conditioner (EPC). TESAT's other product segments include channel amplifiers, filters ...
The simplest klystron tube is the two-cavity klystron. In this tube there are two microwave cavity resonators, the "catcher" and the "buncher". When used as an amplifier, the weak microwave signal to be amplified is applied to the buncher cavity through a coaxial cable or waveguide, and the amplified signal is extracted from the catcher cavity.
A crossed-field amplifier (CFA) is a specialized vacuum tube, first introduced in the mid-1950s and frequently used as a microwave amplifier in very-high-power transmitters. Raytheon engineer William C. Brown 's work to adapt magnetron principles to create a new broadband amplifier is generally recognized as the first CFA, which he called an ...
A backward wave oscillator (BWO), also called carcinotron or backward wave tube, is a vacuum tube that is used to generate microwaves up to the terahertz range. Belonging to the traveling-wave tube family, it is an oscillator with a wide electronic tuning range. An electron gun generates an electron beam that
