Metal-semiconductor field effect transistor (MESFET)
Anadigics

The AGB is one of a series of GaAs MESFET amplifiers designed for use in applications requiring high linearity, low noise and low distortion. With a high IP3, low noise figure and wide band operation, the AGB3301 is ideal for 50Ω wireless infrastructure applications such as MMDS, Cellular Base Stations, PCS and WLL. Offered in a low cost SOT-89 surface mount package, the AGB3301 requires a single +5V to +9V supply, and typically consumes less than 1 Watt of power.
