摘要: | 隨著第五代行動通訊的發展,毫米波的研究與應用已經成為現在的趨勢。然而,對於頻寬及更高的傳輸速率需求與日俱增,現今無線通訊頻率主要在6 GHz以下已經相當飽和,因此往更高頻率設計為重要的技術發展。其中,Ka 頻段及V頻段為第五代行動通訊主要潛在發展頻段。在無線通訊系統中,接收機的設計相當重要及關鍵,本篇論文著重於應用於第五代行動通訊接收器的設計與研究。
本篇論文主要分成兩個部分:第一部分為應用於Ka頻段之65nm CMOS 製程設計低雜訊放大器相關研究。低雜訊放大器在射頻接收前端系統為一重要元件;LTE-Advance Pro中,聚合載波(CA)技術為第五代行動通訊的技術之一,由於聚合載波強調的是通道的使用效率,因此本文將探討低雜訊放大器中線性度的優劣對於聚合載波技術應用上的改善與實現。在64-QAM的調變訊號傳輸中,利用本文提出的低雜訊放大器,三階項抑制的範圍,在500MHz的操作頻寬中皆可大於35 dBr。 第二部分提出了應用於V-band的雙極化接收器。MIMO系統為第五代行動通訊中一個很重要的應用。在本文中提出一個以65nm CMOS 製程設計的接收機系統並與雙極化天線低溫共燒陶瓷做封裝整合,實現MIMO系統在V-band上的應用。本文也將探討,利用天線雙極化的特性,有效的改善了MIMO系統接收資料傳輸相位不匹配的問題。在64-QAM的調變訊號傳輸應用中,進一步將頻譜的使用效率提升至12 Gbps。 With the development of the fifth-generation mobile communication (5G), the research and application of millimeter wave is the current trend. However, the demand for more bandwidth and higher transmission rates is increasing day by day. Recent wireless communication frequency usage is quite saturated below 6 GHz, so designing to higher frequencies is an important technological development. Among them, Ka-band and V-band are the main potential development bands for the fifth-generation mobile communication. In wireless communication systems, the design of the receiver is quite important and critical. This paper focuses on the design and the research of receiver. This thesis is divided into two parts: The first part is the research of a low noise amplifier fabricated in 65-nm CMOS process which is applied in Ka-band. The low noise amplifier is an important component in the radio receiving front-end system. The key development technologies of Long Term Evolution Advanced Professional (LTE-Advance Pro) have been applied in 5G. Carrier aggregation (CA) is a technology in LTE-A; the main purpose of CA is to improve the spectral efficiency. When using CA, the carrier components of different frequency bands are aggregated together which increases the throughput and improve the efficiency. This thesis focuses on the design and research of linearity in low noise amplifier (LNA) for improved CA application. The proposed LNA is experimentally verified by using 64-QAM modulated signals with a third order intermodulation suppression of up to 35dBr at a 500-MHz bandwidth. The second part proposes a V-band dual-polarization receiver. Multi-input multi-output (MIMO) system is an important application in 5G. In this thesis, the dual-polarization antenna is integrated with the receivers through flip chip on the low temperature co-fired ceramic (LTCC) substrate. The receiver front-end is composed of a low noise amplifier and demodulator fabricated in 65-nm CMOS process. The proposed dual-polarization receiver is realized in the V-band MIMO system. This thesis will improve the phase mismatch of transmission data at the receiver terminal by applying the proposed dual-polarization antenna to increase the spectral efficiency. The proposed dual-polarization receiver, the channel as well as spectral efficiency can be up to 12 bit/s/Hz by using 64-QAM modulated signals. |
