Power effiCienCy in wireless CommuniCations
In other words, efficiency is a measure of how well a device converts
one energy source to another. In microwave engineering, we are inter-
ested in converting DC power to RF power. So, efficiency in power
amplifiers describes the part of the DC power that is converted to
RFpower.
e efficiency is one for an ideal power amplifier; this means that
thepower delivered to the load is equal to the power derived fromthe
DC supply, which states that there is no power consumption in the
power amplifier. However, in reality this will not be happening, due to
the fact that there is no fully linear power amplifier in ...
