Low Noise Amplifier with Bypass Mode in Low Profile Package

Currently Viewing:

The Broadcom MGA-655T6 is an economical easy-to-use GaAs MMIC Low Noise Amplifier (LNA) with Bypass mode. The Bypass mode enables the LNA to be bypassed during high input signal power and reduce current consumption.

It's housed in a low profile 2 x 1.3 x 0.4mm 6-pin Ultra Thin Package.


  • Broadband operation (2.5 – 4)GHz
  • Adjustable bias current for gain/IP3 optimization
  • Very low noise figure
  • Bypass mode using a single pin
  • Low current consumption in bypass mode, <100 μA
  • Fully matched to 50 ohm in bypass mode
  • High Linearity in LNA and bypass mode
  • GaAs E-pHEMT Technology[1]
  • Low profile package size: 2.0 x 1.3 x 0.4 mm3
  • Excellent uniformity in product specifications


  • Low noise amplifier for Wimax, Wireless Local Loop
