High Electron Mobility Transistors (HEMT)

 

 

High electron mobility transistors (HEMTs) are used in microwave circuit applications. These transistors behave much like conventional field effect transistors (FETs): a conducting channel between drain and source electrodes can be affected by applying a voltage to the gate electrode. This causes modulation of the drain-source current. In a HEMT, a hetero structure that confines the charge carriers to a thin layer creates the conducting channel. The concentration of the carriers and their speed in this layer enables the transistor to maintain a high gain at very high frequencies.

Products & Services
Transistors are electronic devices made of semiconductor material that amplify a signal or open or close a circuit. Search by Specification | Learn more about Transistors
Metal-oxide semiconductor field-effect transistors (MOSFETs) are electronic switching devices with a conducting channel as the output. An electrode called a gate controls the width of the channel and determines how well the MOSFET conducts. Search by Specification | Learn more about Metal-oxide Semiconductor FET (MOSFET)
Junction field-effect transistors (JFET) consist of a semiconductor channel in which the width and the conductivity of the channel is controlled by the space-charge region associated with the p-n region. Search by Specification | Learn more about Junction Field-Effect Transistors (JFET)
RF MOSFET transistors are metal-oxide semiconductor field-effect transistors (MOSFETs) that are designed to handle high-power RF signals from devices such as stereo amplifiers, radio transmitters, TV monitors, etc. Search by Specification | Learn more about RF MOSFET Transistors
