Radio-frequency (RF) engineering is a subset of electrical engineering involving the application of transmission line, waveguide, antenna, radar, and electromagnetic field principles to the design and application of devices that produce or use signals within the radio band, the frequency range of about 20 kHz up to 300 GHz.

Asad Ali Abidi developed RF CMOS technology at UCLA during the late 1980s to early 1990s.. Pakistani engineer Asad Ali Abidi, while working at Bell Labs and then UCLA during the 1980s–1990s, pioneered radio research in metal–oxide–semiconductor (MOS) technology and made seminal contributions to radio architecture based on complementary MOS (CMOS) switched-capacitor (SC) technology.

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 ...
The IPO of the company on the NASDAQ stock market occurred on June 3, 1997 under the symbol RFMD. [9] At the time of the IPO, the company was a pioneer and leader in the use GaAs HBT process technology for commercial wireless applications, which had benefits in power efficiency, linearity, complexity and size, while also having expertise in older GaAs MESFET and silicon polar transistor ...
Such a device is also called a power device or, when used in an integrated circuit, a power IC. A power semiconductor device is usually used in "commutation mode" (i.e., it is either on or off), and therefore has a design optimized for such usage; it should usually not be used in linear operation.
An RF receiver module receives the modulated RF signal, and demodulates it. There are two types of RF receiver modules: superheterodyne receivers and superregenerative receivers . Superregenerative modules are usually low cost and low power designs using a series of amplifiers to extract modulated data from a carrier wave.
The IGBT accounts for 27% of the power transistor market, second only to the power MOSFET (53%), and ahead of the RF amplifier (11%) and bipolar junction transistor (9%). [235] The IGBT is widely used in consumer electronics, industrial technology, the energy sector, aerospace electronic devices, and transportation.
