Abstract :
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%).
