Low Noise, High Linearity Active Bias Amplifier

Currently Viewing:

Broadcom’ MGA-632P8 is an economical, easyto-use GaAs MMIC Low Noise Amplifier (LNA) with active bias. The LNA has low noise with excellent input return loss and high linearity achieved through the use of Broadcom’ proprietary 0.5um GaAs Enhancement mode pHEMT process. It has an extra feature that allows a designer to adjust supply current and gain externally. This device is optimized for use in the 1.4GHz to 3GHz frequency range.


  • Externally adjustable gain, 15-20db
  • High Linearity performance
  • Low Noise Figure
  • Excellent uniformity in product specification
  • High Isolation


LNA for GSM, CDMA, W-CDMA,  TD-SCDMA & other ultra low noise applications
