MGA-425P8
GaAs Enchancement-mode PHEMT
Power Amplifier in 2x2 mm2 LPCC Package
Data Sheet
Description
Features
Avago 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 Avago Technologies’s proprietary GaAs Enhancementmode pHEMT process.
• Near 50Ω broadband output match
MGA-425P8 is housed in a ­miniature 2.0 x 2.0 x 0.75 mm 8‑lead
leadless-plastic-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.
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.
• Single +3.3V supply
• High Gain & OIP3
• Miniature 2 x 2 x 0.75 mm
LPCC package
• Pb-free & MSL-1 package
• Tape-and-Reel packaging
option available
Specifications @ 5.25 GHz, 3.3V, 58 mA (typ)
• 13.3 dBm Linear Pout @ 5% EVM
• 10.3% PAE @ +13.3 dBm Pout
• 12 dBm Linear Pout @ 3% EVM
• 7.6% PAE @ + 12 dBm Pout
One external resistor (RBias) is used to set the bias ­current of
the device over a wide range.
• 47% PAE @ P1dB
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.
• 32.9 dBm OIP3
