Abstract:

The market for wireless portable devices has grown signicantly over the recent years.Wireless devices with ever-increased functionality require high rate data transmissionand reduced costs. High data rate is achieved through communication standards such asLTE and WLAN, which generate signals with high peak-to-average-power ratio (PAPR),hence requiring a power amplier (PA) that can handle a large dynamic range signal. Tokeep the costs low, modern CMOS processes allow the integration of the digital, analogand radio functions on to a single chip. However, the design of PAs with large dynamicrange

Software radio architecture can support multiple standards by performing analogto- digital (A/D) conversion of the radio frequency (RF) signals and running reconfigurable software programs on the backend digital signal processor (DSP).

博士<br>國立交通大學<br>電信工程研究所<br>104<br>In recent years, a numerous of wireless communication standards were developed. The outdoor network systems have been developed successfully from 2G cellular system to 4G cellular system. In the wireless wide area networks (WWANs), the throughput has been pushed from hundreds of Kbps to tens of Mbps. The indoor network systems have been developed in Bluetooth and WiFi. The throughput has been pushed to tens of Mbps. For hundreds of Mbps application, there are ultra-wideband communication systems. For several Gbps application, there is a wireless HD communicati

碩士<br>國立雲林科技大學<br>電機工程系碩士班<br>101<br>The rapid growth of the Hi-Tech Industry in recent years, wireless communication grew increasingly to popular, allow people to each other are not limited to contact at any time and location. IEEE establish many communications standards, such as: Bluetooth, Wi-Fi (Wireless Fidelity), WiMAX (World-wide Interoperability for Microwave Access), use to provide different bandwidth needs. The wireless receive RF front-end circuit for wireless application circuit, it’s function to receive analog signals, RF front-end circuit consists of low noise amplifier (LNA), mi

碩士<br>國立成功大學<br>微電子工程研究所<br>107<br>This research explores RF components for the LTE-U and FR1 bands, and the advantages of GaN transistors in the IMT-2020 (5G) system standard. The first chapter introduces the research background of this research and the current status of IMT-2020 (5G) communication standards. In second chapter, we design the microstrip line bandpass filter of hairpin structure, the frequency band for 5-6GHz, and expected to be used in Unlicensed spectrum (LTE-U) of 3GPP TS 36.104. The third chapter introduces the power amplifier which using the Pseudomorphic High Electron Mob
