本文提出了一款29GHz分数N频率合成器,适用于5G毫米波通信,实现了-31dBc的集成相位噪声,并支持多个频段以满足后向兼容需求。该设计解决了毫米波频段低相位噪声频率生成的关键问题。
high-bandwidth mobile communications, 5G technology is targeted to support data-rates up to 10Gb/s. To reach this goal, one of challenging tasks for wireless transceivers is to generate millimeter-wave (mmW) band LO signals that have an ultra-low integrated phase noise (IPN). The IPN of an LO signal should be reduced to less than −30dBc to satisfy the EVM requirements of high-order modulations, such as 64-QAM. Figure 23.1.1 shows the frequency spectrum for cellular systems, including existing bands below 6GHz and new mmW bands for 5G. A key goal of the evolution of mobile communications is to ensure interoperability with past-generation standards, and this is expected to continue for 5G. Thus, LO generators eventually will be
