yes / This paper describes the characterization and design of
energy efficient user terminal transceiver power amplifier. To
reduce the design of bulky external circuitry, the load modulation
technique is employed. The design core is based on the
combination of Class B and Class C that includes quarter
wavelength transformer at the output to perform the load
modulation. The handset transceiver for this power amplifier is
designed to operate over the frequency range of 3.4GHz to
3.6GHz mobile WiMAX band. The performances of the load
modulation amplifier are compared with conventional Class B
amplifier. The results of 30dBm output power and 53% power
added efficiency are achieved.
