Agilent MGA-425P8
GaAs Enchancement-mode
PHEMT Power Amplifier in
2x2 mm2 LPCC Package
Data Sheet
Features
• Near 50Ω broadband output match
• Single +3.3V supply
Description
Agilent Technologies’s MGA-425P8
power amplifier is designed for
wireless application in the
2–10 GHz frequency range. The PA
has a high power efficiency (PAE)
achieved through the use of Agilent
Technologies’s proprietary GaAs
Enhancement-mode pHEMT process.

This allows the designer to use the
same part in several circuit positions and tailor the output power/
linearity performance, and current
consumption, to suit each position.
• 13.3 dBm Linear Pout @ 5% EVM
Pin 8 (NC)
Ibias
One external resistor (RBias) is
used to set the bias current of the
device over a wide range.

• 7.6% PAE @ + 12 dBm Pout
Pin 1 (NC)
Pin 2 (RFin)
On-chip bias circuitry allows
operation from a single +3.3V
power supply. The output of the
amplifier is near to 50Ω (below 2:1
VSWR) around 4.9–5.8 GHz. This
makes MGA-425P8 an ideal choice
as power amplifier for broadband
IEEE 802.11a system as well as
other high performance wireless
application in the 2–10 GHz
frequency range.
• Miniature 2 x 2 x 0.75 mm
LPCC package
2.0 x 2.0 x 0.75 mm 8-lead LPCC
Pin 4 (NC)
MGA-425P8 is housed in a miniature
2.0 x 2.0 x 0.75 mm 8-lead leadlessplastic-chip-carrier (LPCC) package.
The compact footprint, low profile
couple with the excellent thermal
efficiency of the LPCC package
makes the MGA-425P8 an ideal
choice as power amplifier that saves
board space.

taken from 3 different wafers and 3 different
lots. Future wafers allocated to this product
may have nominal values anywhere between
the upper and lower limits.
6. Measurements are made on production test
board, which represents a trade-off between
optimal OIP3, P1dB, Gain and VSWR. Circuit
losses have been de-embedded from actual
measurements.
