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 .
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 .
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 ]
In October 2000, Herley acquired American Microwave Technologies (AMT) in Anaheim, California, a manufacturer of solid-state broadband RF amplifiers used by the scientific and medical markets. [ 1 ] In September 2002, Herley acquired EW Simulation Technology Ltd., a UK manufacturer of electronic warfare simulator systems, increasing Herley's ...
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 ...
The Crown DC300, introduced in 1967, helped define the era of modern power amplifiers [5] In 1959, Crown began making standalone tube power amplifiers. By 1963, solid state electronics development allowed Crown to produce a more robust tape recorder, and in 1964, their first solid state power amplifier: the low-profile SA 20-20. [2]
The silicon-based RF LDMOS (radio-frequency LDMOS) is the most widely used RF power amplifier in mobile networks, [2] [3] [4] enabling the majority of the world's cellular voice and data traffic. [5] LDMOS devices are widely used in RF power amplifiers for base-stations as the requirement is for high output power with a corresponding drain to ...
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 ...
