摘要： The invention may be embodied in radio frequency power amplifier (RF-PA) predriver circuits employing a hybrid analog/digital RF architecture including a resynchronizing digital-to-analog convertor to drive an efficient high-power output stage suitable for driving standard high power amplifier (HPA) output devices. The hybrid analog/digital RF architecture retains the advantages of high digital content integration found in conventional Class-S architecture, while relaxing the performance requirements on the output transistors and on the bitstream generator. The resulting predriver circuit combines the VLSI integration benefits of digital designs with the extensibility to arbitrary output power levels characteristic of analog designs. The hybrid analog/digital driving circuit is well suited for use with analog and Class-S HPAs used in wireless communication systems, such as the Doherty type HPA.
