0.5 – 6 GHz Low Noise Amplifier
Data Sheet
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 Ω. 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 VD terminal.
A simple external bias insertion circuit consisting of a
shunt inductor and a series dc block capacitor is suf-
ficient 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.
