摘要

本文提出了一种用于射频前端的宽带阻断滤波技术。宽带LNA和传输阻抗滤波器作为接收机的一部分来实现，以证明系统的可行性。前端增益为43 dB和41 dB，噪声系数为3.2 dB和5.7 dB, IIP3分别为- 13和- 5 dBm，传输阻抗滤波器分别关闭和打开。采用本文所述的结构，可获得6 dB的选择性增益。

Wideband 2 to 6GHz RF front-end with blocker filtering

This paper presents a wideband blocker filtering technique for a RF front-end. The wideband LNA and the transferred impedance filter are implemented as part of a receiver to demonstrate the feasibility of the system. The front-end achieves a gain of 43 and 41 dB, noise figure of 3.2 and 5.7 dB with IIP3 of −13 and −5 dBm with the transferred-impedance filter turned off and on, respectively. Added selectivity of 6 dB is achieved by using the structure described in this paper.
