摘要

本文报道了一种多模低噪声放大滤波器（LNAF）的设计和实际开发，该滤波器具有单频段、并发双频段和内在关断模式，其通带模式具有连续带宽（BW）可调谐。提出的多模LNAF概念基于一种新型多模射频（RF）组件，该组件由一个晶体管和两个复杂匹配带通滤波器（bpf）组成，从而消除了射频前端（RFFE）额外滤波的需要。通过重新分配传输零（TZ）和重新配置晶体管的偏置电压，可以从本质上关闭bpf，从而重新配置其工作模式。由于对噪声系数（NF）的影响最小，TZ的灵活性也被用于BW调谐。通过设计、制造和测试一个双模LNAF和两个四模LNAF原型（LNAFs I和II），在5G FR1频带n77和n79上验证了多模LNAF概念，这两个原型具有可调谐的BW和关闭操作模式，可以实现单频段和并发双频传递函数。

Multimode Low Noise Amplifier Filter With Tunable Transfer Function Characteristics

This article reports on the design and practical development of a multimode low noise amplifier filter (LNAF) capable of single band, concurrent dual band, and an intrinsic switch-off mode of operation with continuous bandwidth (BW) tunability in its passband modes. The proposed multimode LNAF concept is based on a new type of multimode radio frequency (RF) component that comprises a transistor and two complex-matched bandpass filters (BPFs), thus eliminating the need for additional filtering in the RF front end (RFFE). Its modes of operation can be reconfigured by intrinsically switching off the BPFs through transmission zero (TZ) re-allocation and by reconfiguring the transistors’ bias voltages. The TZ flexibility is also exploited for BW tuning due to its minimal impact on the noise figure (NF). The multimode LNAF concept was validated at the 5G FR1 frequency bands n77 and n79 through the design, manufacturing, and testing of one dual-mode LNAF and two quad-mode LNAFs (LNAFs I and II) prototypes that functionalize single-band and concurrent dual-band transfer functions with tunable BW, and switch-off modes of operation.

期刊介绍： The IEEE Transactions on Microwave Theory and Techniques focuses on that part of engineering and theory associated with microwave/millimeter-wave components, devices, circuits, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, and industrial, activities. Microwave theory and techniques relates to electromagnetic waves usually in the frequency region between a few MHz and a THz; other spectral regions and wave types are included within the scope of the Society whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design.
