MGA-425P8

GaAs Enchancement-mode PHEMT  

Data Sheet

Description

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 AvagoTechnologies’s proprietary GaAs Enhancement-

mode pHEMT process.

MGA-425P8 is housed in a miniature 2.0 x 2.0 x 0.75 mm 8-lead

leadless-plastic-chip-carrier(LPCC)package.Thecompactfoot-

print, 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 (be-

low 2:1VSWR) 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.

One external resistor (RBias) is used to set the bias current of

the device over a wide range.

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.
