Agilent MGA-425P8

GaAs Enchancement-mode

PHEMT Power Amplifier in

2x2 mm2 LPCC Package

Data Sheet

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.

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.

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 posi-

tions and tailor the output power/

linearity performance, and current

consumption, to suit each position.

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.
