Description
Hewlett-Packard’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. Current
consumption is only 4.5 mA,
making this part ideal for battery
powered designs.
