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.
