MGA-231T6

MGA-231T6 High-Gain GPS LNA with Variable Current and Shutdown Function Data Sheet Description Avago Technologies’ MGA-231T6 is a low-noise amplifier (LNA) designed for GPS/ISM/Wimax applications in the (0.9-3.5)GHz frequency range. The LNA uses Avago Technologies’ proprietary GaAs Enhancement-mode pHEMT process to achieve high gain with very low noise figure and high linearity. Noise figure distribution is very tightly controlled. A CMOS-compatible shutdown pin is included either for turning the LNA on/off or for current adjustment. The low noise figure and high gain, coupled with low current consumption make it suitable for use in critical lowpower GPS applications or during low-battery situations.
