MGA-31289

MGA-31289 0.25W High Gain Driver Amplifier 1500 - 3000 MHz Data Sheet Description Avago Technologies MGA-31289 is a 0.25W high gain driver amplifier MMIC with good gain flatness, housed in a standard SOT-89 plastic package. The device features high linearity performance, excellent input and output return loss, and low noise figure. The device can be easily matched to obtain optimum power and linearity. MGA-31289 is externally tunable to operate within 1.5GHz to 3GHz frequency range applications. With high IP3, low noise figure and wideband operation, MGA-31289 may be utilized as a driver amplifier in the transmit chain and as a second stage LNA in the receive chain. This device uses Avago Technologies proprietary 0.25um GaAS Enhancement mode PHEMT process.
