MILMEGA is a company specializing in designing and manufacturing high-power amplifiers for electromagnetic compatibility (EMC) testing. [1] Headquartered in Ryde on the Isle of Wight in England, MILMEGA mainly provides broadband amplifier products with frequency ranges from 80 MHz to 8 GHz , [ 2 ] with power levels from 30W - 1kW .
The inductive output tube (IOT) or klystrode is a variety of linear-beam vacuum tube, similar to a klystron, used as a power amplifier for high frequency radio waves. It evolved in the 1980s to meet increasing efficiency requirements for high-power RF amplifiers in radio transmitters. [ 1 ]
A radio-frequency power amplifier (RF power amplifier) is a type of electronic amplifier that converts a low-power radio-frequency (RF) signal into a higher-power signal. [1] Typically, RF power amplifiers are used in the final stage of a radio transmitter , their output driving the antenna .
In January 2000, Herley acquired Robinson Labs in Nashua, New Hampshire, a manufacturer of microwave components used in commercial wireless and defense applications. [ 1 ] In October 2000, Herley acquired American Microwave Technologies (AMT) in Anaheim, California , a manufacturer of solid-state broadband RF amplifiers used by the scientific ...
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 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 ...
From 1993 until RFMD built its own semiconductor fabrication plant in 1998, it used TRW as a contract manufacturer while TRW acquired a 10% ownership interest in the company. [8] GaAs HBT emerged as a leading technology for high-performance RF applications, such as power amplifiers and small signal devices used in cellular handsets. [8]
Qorvo was created on January 1, 2015, with the merger of TriQuint Semiconductor and RF Micro Devices (RFMD). [4] In June 2015, the new company became a component of the S&P 500 . [ 7 ] At the time of joining the S&P 500, Qorvo was valued at $12 billion. [ 7 ]
