General Description
The HMC278MS8G is a 100mW GaAs MMIC
medium power amplifier covering 1.7 to 3 GHz. The
device is packaged in a low cost, surface mount 8
lead MSOP plastic package with an exposed base
paddle for improved RF ground and thermal dissi-
pation. The self-biased amplifier provides 21 dB of
gain and +20 dBm P1dB output power while operat-
ing from a single positive supply of Vdd= +5V @
130 mA. At Vdd = +3V the gain is 19 dB with a
P1dB of +16dBm. With RF I/Os matched to 50 Ohm,
external component requirements are minimal. At
a height of 0.040” (1.0mm), the MSOP8 package
is ideal for low profile portable wireless devices.
Use the HMC278MS8G with the HMC309MS8 inte-
grated LNA/TxRx switch front-end for BLUETOOTH
Class I, HomeRF, 802.11 WLAN, and ISM 2.4 GHz
radios.
