Yes / Fourth generation systems require the use of both
amplitude and phase modulation to efficiently utilize the
available spectrum and to obtain high data rates, hence imposing
stringent requirements on the power amplifier in terms of
efficiency and linearity and requires the power amplifier to
operate linearly and efficiently. The B3G base station transceiver
Doherty power amplifier was designed to operate over the
frequency range of 3.47GHz to 3.53GHz mobile WiMAX band
using Freescale¿s N-Channel Enhancement-Mode Lateral
MOSFET Transistor, MRF7S38010HR3; The performances of
the Doherty amplifier are compared with that of the conventional
Class AB amplifier. The results of 43 dBm output power and
66% power added efficiency are achieved.
