General Description
The HMC921LP4E is a high linearity GaAs HBT
MMIC 2 watt power amplifier operating from 0.4 to
2.7 GHz and is housed in a RoHS compliant 4x4 mm
QFN leadless package. The HMC921LP4E utilizes
a minimum number of external components and
operates from a single +5V supply. This versatile
power amplifier can be biased for both low quiescent
current and high quiescent current modes by adjusting
a single external resistor.
