线性前端模块用于4G/5G LTE高级应用

Abstract: 摘要

With explosive band proliferation as well the use of carrier aggregation (CA), multiple input multiple output (MIMO) techniques and 5G, research in the area of improving the cost, performance and the size of RF transmit solutions is very active with many developments over the past few years.

近年来，随着频带的爆炸式增长以及载波聚合(CA)、多输入多输出(MIMO)技术和5G技术的应用，在提高射频发射解决方案的成本、性能和尺寸方面的研究非常活跃 The proliferation of worldwide smartphones has been in part possible due to increase computational power of CMOS technology in lower feature nodes as 7nm/14nm. 全球智能手机的普及在一定程度上是由于CMOS技术在低特征节点(如7nm/14nm)上的计算能力提高

This has also made it possible to enhance RF CMOS through digital signal processing (DSP) and digital calibration.

这也使得通过数字信号处理(DSP)和数字校准来增强射频CMOS成为可能

Despite this progress there is a shift in terms of what parts of the RF system are portioned in advanced CMOS nodes and what blocks are left and integrated together with other analogue and RF blocks in a front-end module (FEM).

尽管取得了这些进展，但在先进的CMOS节点中分配了射频系统的哪些部分，以及在

前端模块(FEM)中留下哪些块并与其他模拟块和射频块集成在一起，这些方面都发生了变化

This paper proposes a solution for this partitioning for lower cost and size and with high linearity performance and low noise which is mandatory for new 4G/5G multimode multiband (MMBA) FEM module.

针对4G/5G多模多频(MMBA)有限元新模块的要求，提出了一种低成本、低尺寸、高线性、低噪声的分区方案

A 2.3GHz - 2.7GHz broadband CMOS FDD/TDD LTE Band 7, 38, 40 and 41 power amplifier (PA) fully integrated with a fast envelope tracker (ET) on a single 0.18μm CMOS die is presented, as well a method to integrate with a 4G/5G FEM.

2.3 ghz - 2.7 ghz宽带CMOS FDD / TDD LTE乐队7,38岁,40和41功率放大器(PA)完全集成的快速包络跟踪(ET)在一个0.18μm CMOS模,以及一个方法来集成4 g / 5 g有限元法

The CMOS PA and the tracker achieve a 37% overall efficiency for 26.5dBm and -39dBc ACLR1.

CMOS PA和跟踪器在26.5dBm和-39dBc ACLR1上实现了37%的总效率

This paper also presents how this module integrates into a full 4G/5G FEM for mobile applications.
