Data Sheet

Description

Avago’s MGA-87563 is an economical, easy-to-use GaAs

MMIC amplifier that offers low noise and excellent gain

for applications from 0.5 to 4 GHz. Packaged in an ultra-

miniature SOT-363 package, it requires half the board

space of a SOT-143 package.

With the addition of a simple shunt-series inductor at the

input, the device is easily matched to achieve a noise of

1.6 dB at 2.4 GHz. For 2.4 GHz applications and above, the

output is well matched to 50 Ohms. Below 2 GHz, gain

can be increased by using conjugate matching.

The circuit uses state-of-the-art PHEMT technology with

self-biasing current sources, a source-follower interstage,

resistive feedback, and on-chip impedance matching

networks. A patented, on-chip active bias circuit allows

operation from a single +3 V or +5 V power supply. Cur-

rent consumption is only 4.5 mA, making this part ideal

for battery powered designs.
