+17 dBm Psat at 2.0 GHz
• Single +3V Supply
Description
Agilent’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 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.
• 2.8 dB Noise Figure at
2.0 GHz
• 12.4 dB Gain at 2.0 GHz
• Ultra-miniature Package
• Unconditionally Stable
Applications
Pin Connections and
Package Marking
• Buffer or Driver Amp for
PCS, PHS, ISM, SATCOM
and WLL Applications
• High Dynamic Range LNA

The output of the amplifier is
matched to 50Ω (better than
2.1:1 VSWR) across the entire
bandwidth. The input is partially
matched to 50Ω (better than
2.5:1 VSWR) below 4 GHz and
fully matched to 50Ω (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 IP3.
