Abstract

With increasing consumer demand for wireless devices to support multiple air standards and applications, there have been increased trends for the implementation multiband (MB) power amplifier (PA) for wireless handsets. This paper presents a novel design of an MB PA based on an industry-standard 130nm process technology. PAs using conventional transformer based matching has a narrow bandwidth. Hence, a PA using cascode differential architecture with novel single primary and double secondary transformer matching is proposed in this design. The proposed PA has wider 3dB bandwidth from 1GHz-2. 3GHz covering 11 LTE FDD frequency bands. The PA has 22. 5dB gain with peak output power of 28. 4dBm. The PA is operated in class-AB linear mode; and PAE of 37% at 1-dB compression point and 65% at peak output power is achieved. The achieved ACPR is-42. 6dBc which is well confined within the modern LTE linearity specifications.
