摘要

目前4G基站收发器的主要挑战之一是在发射器和接收器之间实现足够高的射频隔离。通常需要一个大而昂贵的空腔滤波器设计。我们提出了一种新颖的小尺寸接收频带自干扰消除放大器解决方案，可以将滤波要求降低到40dB，从而显着减小滤波器尺寸(例如30…40%)。

Small size receiver band self-interference cancellation amplifier for 4G transceivers

One of the main challenges in 4G base station transceivers today is to achieve high enough RF isolation between the transmitter and the receiver. Conventionally a large and expensive cavity filter design is required. We propose a novel small size receiver band self-interference cancellation amplifier solution that can reduce the filtering requirements up to 40dB and thus reduce filter size significantly (e.g. 30...40%).
