Description
Hewlett-Packard’s MGA-86563 is
an economical, easy-to-use GaAs
MMIC amplifier that offers low
noise figure and excellent gain for
applications from 0.5 to 6 GHz.
Packaged in an ultra-miniature
SOT-363 package, it requires half
the board space of the SOT-143.
The MGA-86563 may be used
without impedance matching as a
high performance 2 dB NF gain
block. Alternatively, with the
addition of a simple shunt-series
inductor at the input, the device
noise figure can be reduced to
1.6␣ dB at 2.4 GHz. For 1.5 GHz
d
applications and above, the
output is well matched to 50 Ω.
Below 1.5 GHz, gain can be
increased by using conjugate
matching.
The circuit uses state-of-the-art
PHEMT technology with selfbiasing current sources, a sourcefollower interstage, resistive
feedback, and on-chip impedance
matching networks. A patented,
on-chip active bias circuit allows
operation from a single +5 V
power supply. Current consumption is only 14 mA, making this
part suitable for battery powered
applications.
