Description
Hewlett-Packard’s MGA-81563 is
an economical, easy-to-use GaAs
MMIC amplifier that offers
excellent power and low noise
figure for applications from 0.1 to
6 GHz. Packaged in an ultra-
miniature SOT-363 package, it
requires half the board space of a
SOT-143 package.
The output of the amplifier is
matched to 50
Ω
(better than
2.1:1 VSWR) across the entire
bandwidth. The input is partially
matched to 50
Ω
(better than
2.5:1 VSWR) below 4 GHz and
fully matched to 50
Ω
(better than
2:1 VSWR) above. A simple series
inductor can be added to the input
to improve the input match below
4 GHz. The amplifier allows a
wide dynamic range by offering a
2.7 dB NF coupled with a +27 dBm
Output IP
3
.
The circuit uses state-of-the-art
PHEMT technology with proven
reliability. On-chip bias circuitry
allows operation from a single
+3 V power supply, while resistive
feedback ensures stability (K>1)
over all frequencies and
temperatures.
