Functional Diagram
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.
