RF FETs, otherwise known as Radio Frequency Field-Effect Transistors, are a type of discrete semiconductor device that play a pivotal role in several modern electronics. They act as a switch or an amplifier within electronic circuits, regulating electrical behavior. These products, using voltage to control the flow of current, are integral for the function of devices varying from radios and televisions to essential telecommunications equipment. The nature and precision of RF FET's make them specifically apt for high-frequency applications like Wi-Fi, RF power amplifiers in wireless communication devices, radar systems, and satellite communications, where they ensure seamless and stable transmission.
The main characteristics of RF FETs include their high input impedance, which allows for excellent voltage control, and their ability to handle strong signal strength without distortion, thanks to their high power gain. Manufacturers like NXP Semiconductors, Infineon Technologies, and Qorvo are leading the market in RF FET production.
