Abstract
This paper presents the design approach, realization and measurement results of a compact driver multi-stages 3-way fully integrated Doherty MMIC 60W power amplifier for true dual-band operation using LDMOS technology. Those results are achieved thanks to the Cds cancellation technic for the combiner design to achieve wideband impedance transformation combined with the 3-way DPA architecture to reach high efficiency in deep back-off and reduce load modulation. Through this design a dedicated attention is put to extend PA video bandwidth thanks to integrated passive device to handle simultaneous digital pre-distortion linearization in B1 and B3, 4G/4.5G telecommunication band. This device is highly linear, after digital pre-distortion ACLR of −56dBc are measured for 2cLTe20MHz 8dB PAR spaced by 345MHz at 35dBm, 12dB OBO, while efficiency is above 29%. Moreover, LDMOS technology is a mature process, consequently this MMIC is a reliable low-cost PA solution for mass production in a very compact package.
