The number of available services in mobile devices has increased continuously over the past several years. Applications such as the 5G cellular network, Wi-Fi, Bluetooth, and GPS are standard in modern devices. As a result, RF front-end requirements have become increasingly complex. To save money and space, it can make sense to use one front end for several services, which requires components with an increased bandwidth. Because of the high bandwidth used, the filtering of unwanted signals is no longer possible in many cases. This makes a high linearity of active components, such as amplifiers and mixers, even more important as they can become sensitive to intermodulation. In addition, the power consumption of the components must be as low as possible since today's users demand long battery life from their mobile devices. Therefore, wideband low-noise amplifiers (LNAs) with a high linearity and low input power are required.

组件线性度和功率效率：Sub-6 5G 灵活低干扰接收器

在过去几年中，移动设备中可用服务的数量不断增加。5G 蜂窝网络、Wi-Fi、蓝牙和 GPS 等应用是现代设备的标准配置。因此，射频前端要求变得越来越复杂。为了节省资金和空间，将一个前端用于多项服务是有意义的，这需要具有更高带宽的组件。由于使用了高带宽，在许多情况下不再可能过滤不需要的信号。这使得放大器和混频器等有源组件的高线性度变得更加重要，因为它们可能对互调变得敏感。此外，组件的功耗必须尽可能低，因为今天的用户要求他们的移动设备具有较长的电池寿命。所以，
