1 MGA W High Linearity Driver Amplifier Data Sheet Description Avago Technologies MGA is a high linearity driver MMIC Amplifier housed in a standard QFN 3X3 16 lead plastic package. It features high gain, low operating current, low noise figure with good input and output return loss. Power consumption can be further reduced by reducing the quiescent bias current using two external bias resistors. The device can be easily matched at different frequencies to obtain optimal linearity performance at those frequencies. MGA is especially ideal for 5 wireless infrastructure application operating from DC to 2 GHz frequency range. With the high linearity, excellent gain flatness and low noise figure the MGA may be utilized as a driver amplifier in the transmit chain and as a second stage LNA in the receiver chain. This device uses Avago Technologies proprietary.25 m GaAs Enhancement mode PHEMT process.
