Description
Agilentâs MGA-85563 is
an easy-to-use GaAs RFIC
amplifier that offers low noise
figure and high gain from 0.8 to
6 GHz. Packaged in an ultra-
miniature SOT-363 package, it
requires half the board space of a
SOT-143 package.
The MGA-85563 features a
minimum noise figure of 1.6 dB
and associated gain of 18 dB at
1.9 GHz. The output is matched
internally to 50 â¦, and the input is
partially matched, requiring only
a single external inductor for
optimal performance. The supply
current can be adjusted using an
external resistor, varying IP3
from +12 dBm to +17 dBm.
The circuit uses state-of-the-art
PHEMT technology with proven
reliability. On-chip bias circuitry
allows operation from a single
+3 V supply, while resistive
feedback ensures stability (K > 1)
over frequency and temperature.
