Functional Diagram
General Description
The HMC279MS8G is a +3V GaAs MMIC driver
amplifier covering the 2.5 - 4.2 GHz frequency
range. The device is packaged in a low cost, sur-
face mount MSOP plastic package with an exposed
base paddle for improved RF ground. The ampli-
fier 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 amplifier occupies less than 0.023 sq. in.
(14.6 sq. mm). All data is taken with the ampli-
fier assembled into a 50 ohm test fixture with the
exposed ground paddle connected to RF ground.
Electrical Specifications, TA = +25° C, Vdd= +3V
