Description Features
Avagos MGA-87563 is an economical, easy-to-use GaAs Lead-free Option Available
MMIC amplifi er that off ers low noise and excellent gain
Ultra-Miniature Package

miniature SOT-363 package, it requires half the board
space of a SOT-143 package. 12.5 dB Gain at 2.4 GHz
Single +3 V or 5 V Supply, 4.5mA Current
With the addition of a simple shunt-series inductor at the
input, the device is easily matched to achieve a noise of
Applications
1.6 dB at 2.4GHz. For 2.4 GHz applications and above, the
output is well matched to 50 Ohms. Below 2GHz, gain LNA or Gain Stage for PCS, ISM, Cellular, and GPS
can be increased by using conjugate matching. Applications
The circuit uses state-of-the-art PHEMT technology with
self-biasing current sources, a source-follower interstage,

networks. A patented, on-chip active bias circuit allows
operation from a single +3 V or +5V power supply. Cur-
rent consumption is only 4.5 mA, making this part ideal
