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.
