Description
Hewlett-Packard鈥檚 MGA-86576 is
an economical, easy-to-use GaAs
MMIC amplifier that offers low
noise and excellent gain for
applications from 1.5 to 8 GHz.
The MGA-86576 may be used
without impedance matching as a
high performance 2 dB NF gain
block. Alternatively, with the
addition of a simple series
inductor at the input, the device
noise figure can be reduced to
1.6 dB at 4 GHz.
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
consumption is only 16 mA.
These devices are 100% RF tested
to assure consistent performance.
