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,
surface mount MSOP plastic package with an
exposed base paddle for improved RF ground.
The amplifier provides greater than 36dB gain
and +14 dBm P1dB while operating from a single
+3V supply at only 60mA. This amplifier is ideal
for use in MMDS 2.6-2.7GHz, 3.5 GHz WLL,
and 3.7 - 4.2 GHz satellite receive and transmit
bands. 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 amplifier
assembled into a 50 ohm test fixture with the
exposed ground paddle connected to RF ground.

Guaranteed Performance, Vdd = +3V, -40 to +85 deg C
