Description
Agilent’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
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 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 +5 V
power supply. Current consump-
tion is only 14 mA, making this
part suitable for battery powered
applications.
