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. [3]
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]
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]
The bandwidth of the helix TWT can be as high as two octaves, while the cavity versions have bandwidths of 10–20%. [2] [3] Operating frequencies range from 300 MHz to 50 GHz. [2] [3] The power gain of the tube is on the order of 40 to 70 decibels, [3] and output power ranges from a few watts to megawatts. [2] [3]
pSemi (formerly Peregrine Semiconductor), is a San Diego–based manufacturer of high-performance RF (radio frequency) CMOS integrated circuits.A Murata Manufacturing company since December 2014, the company's products are used in aerospace and defense, broadband, industrial, mobile wireless device, test and measurement equipment and wireless infrastructure markets.
