摘要

本文提出了一种无电感式移动无线电接收机。在接收器的输入端采用8路带通滤波器来提供TX泄漏抑制。该接收器专为LTE和UMTS较低频段设计，并进行了32 MHz双工距离的最坏情况测试。该滤波器可编程为交易的噪声降低为TX抑制。当噪声降低0.3 dB时，IIP2和IIP3分别可达到17和11 dB。该接收器采用28纳米CMOS技术制造。

An inductor-less LTE receiver using an 8-path filter for TX leakage suppression

In this paper, an inductor-less mobile radio receiver is proposed. An 8-path band pass filter is employed at the input of the receiver to provide TX leakage suppression. The receiver is designed for LTE and UMTS lower bands and tested for worst case duplex distance of 32 MHz. The filter can be programmed to trade the noise degradation for TX suppression. For 0.3 dB noise degradation, IIP2 and IIP3 improvements can reach 17 and 11 dB respectively. The receiver has been fabricated in a 28 nm CMOS technology.
