MGA-684P8

MGA-684P8 Low Noise Active Bias Low Noise Amplifier Data Sheet Description Avago Technologies’ MGA-684P8 is an economical, easyto-use GaAs MMIC Low Noise Amplifier (LNA). The LNA has low noise and high linearity achieved through the use of Avago Technologies’ proprietary 0.25 m GaAs Enhancement-mode pHEMT process. It is housed in a miniature 2.0 x 2.0 x 0.75 mm3 8-pin Quad-Flat-Non-Lead (QFN) package. It is designed for optimum use from 1.5 GHz up to 4 GHz. The compact footprint and low profile coupled with low noise, high gain and high linearity make the MGA-684P8 an ideal choice as a low noise amplifier for cellular infrastructure for GSM and CDMA. For optimum performance at lower frequency from 450 MHz up to 1.5 GHz, MGA-683P8 is recommended. Both MGA-683P8 and MGA-684P8 share the same package and pinout configuration.
