Low Noise Amplifier with Bypass/Shutdown Mode

Currently Viewing:

The Broadcom MGA-645T6 is an economical, easy-to-use GaAs MMIC Low Noise Amplifier,  LNA, with a Bypass / Shutdown mode. The LNA features low noise and high linearity.

The Bypass/Shutdown mode enables the LNA to be bypassed during high input signal power and to reduce current consumption.

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