HMC279MS8G

GaAs MMIC DRIVER AMPLIFIER

2.5 - 4.2 GHz

Features

High Gain: 36 dB

Psat Output Power: +14 dBm

Single Supply: +3V @ 60 mA

Ultra Small Package: MSOP8G

No External Matching Required

General Description

The HMC279MS8G is a +3V GaAs MMIC driver ampli­fi er covering the 2.5 - 4.2 GHz frequency range. The
device is packaged in a low cost, surface mount MSOP
plastic package with an exposed base paddle for
improved RF ground. The amplifi er provides greater
than 36dB gain and +14 dBm P1dB while operating
from a single +3V supply at only 60mA. No external
components are required and the amplifi er occupies
less than 0.023 sq. in. (14.6 sq. mm). All data is taken
with the amplifi er assembled into a 50 ohm test fi xture
with the exposed ground paddle connected to RF
ground.

The circuit board used in the fi nal application should
use RF circuit design techniques. Signal lines should
have 50 ohm impedance while the package ground
leads and exposed paddle should be connected
directly to the ground plane similar to that shown. A
suffi cient number of VIA holes should be used to con­nect the top and bottom ground planes. The evalua­tion circuit board shown is available from Hittite upon
request.
