MGA-665P8

GaAs Enhancement-Mode

PHEMT 0.5 – 6 GHz Low Noise Amplifier

Data Sheet

Surface Mount, 2.0 x 2.0 x 0.75 mm 8-lead LPCC

Description

Avago’s MGA-665P8 is an economical, easy-to-use

GaAs MMIC Low Noise Amplifier (LNA) with a unique

active-low power-down function. The LNA has low

noise figure and high gain achieved through the use of

Avago Technologies’ proprietary GaAs Enhancement-

mode PHEMT process. It is housed in a miniature 2.0 x

2.0 x 0.75 mm 8-pin Leadless-Plastic-Chip-Carrier

(LPCC) package. The compact footprint and low profile

coupled with low noise, high gain and high linearity

makes the MGA-665P8 an ideal choice as an LNA for

broadband general-purpose applications. Its excellent

broadband isolation also makes it a good buffer amplifier.

The output of the MGA-665P8 provides a very good

broadband match to 50 . Its input requires a simple

external LC network to provide a low noise figure and

good input return loss. Power supply voltage is applied

to both the output terminal and a separate V

A simple external bias insertion circuit consisting of a

shunt inductor and a series dc block capacitor is

sufficient to apply power supply voltage to the output

of the MGA-665P8. The MGA-665P8 provides typical

device performance of 1.45 dB noise figure, 16 dB

gain and an OIP3 of +18.1 dBm at 5.25 GHz, at a bias

point of 3 V and 20.5 mA.
