The device required simple matching components to achieve optimum performance within specific 100 to 200 MHz bandwidth. MGA-31589 is especially ideal for wireless infrastructure applications that operate within the 450 MHz to 1.5 GHz frequency range. With high IP3 and low noise figure, the MGA-31589 may be utilized as a driver amplifier in the transmit chain and as second or third stage LNA in the receive chain. For optimum performance at higher frequency from 1.5 GHz to 3.0 GHz, MGA-31689 is recommended. MGA-31589’s high gain and high linearity features are achieved through the use of Avago Technologies’ proprietary 0.25 mm GaAs Enhancement-mode pHEMT process.
