With the opening of the multi-media communication era, high-speed communication systems with a bit rate of more than several hundreds Mb/s are being built in optical fiber networks. Millimeter-waves have also attracted much attention for the constructions of wireless communication systems having such high bit rate. Having this fact in mind, we have developed a high resolution video signal distribution system for wall-hanging displays based on the millimeter-wave wireless technology. Since millimeter-wave front ends play key role in such systems, the transmitter and receiver have been fabricated by using our NRD guide technology that promises to provide a high-performance millimeter-wave integrated circuits. NRD guide transceiver, fabricated for wireless LAN at 60GHz, has great advantages such as high speed operation beyond 400Mbps as well as small size less than that of the name card. With this in mind, Giga-bit based transmitter and receiver have been developed for applications to the … More IEEE 1394 and SDI systems. The transmitter consists of Gunn diode oscillator with the output power of 12dBm, ASK modulator made by Schottky barrier diode, and circulator, while the receiver consists of local Gunn diode oscillator with the LO power of 10dBm and balanced mixer with the conversion loss of 12dB. Millimeter-wave with the frequency of 59.75GHz is modulated by the 1Gbps clock in the NRD guide ASK transmitter, and the demodulated wave which is received by the NRD guide receiver separated by a distance of about 5mm in a narrow hall is down-converted to the intermediate frequency (IF) of 2.25GHz. And then the IF wave is amplified and detected. The modulating and demodulated wave forms, observed by oscilloscope are identical in shape, thus, it is confirmed that the transmitted signal can be clearly recovered in the receiver. The transmitter and receiver can be applied to wireless portion in IEEE1394 systems and SDI-based HDTV signal distribution systems. New type of millimeter-wave antenna which are simple in shape but multifunctional in performance have been also proposed. The antenna has notable advantage of changeable radiation pattern from wide beam to narrow beam by using simple manner. Thus, the wide beam and narrow beam antennas can be built in the transmitter and receiver for base station use and information terminal use, respectively. Less

随着多媒体通信时代的到来，在光纤网络中建立了比特率超过几百Mb/s的高速通信系统。由于毫米波具有如此高的比特率，无线通信系统的构建也引起了人们的广泛关注。考虑到这一点，我们开发了一种基于毫米波无线技术的高分辨率壁挂式显示器视频信号分配系统。由于毫米波前端在此类系统中起着关键作用，因此使用我们的NRD制导技术制造了发射器和接收器，该技术有望提供高性能毫米波集成电路。NRD引导收发器是为60GHz无线局域网制造的，具有400Mbps以上的高速运行和比名片还小的体积等优点。考虑到这一点，基于千兆比特的发射器和接收器已经开发用于…更多的IEEE 1394和SDI系统。发射端由输出功率12dBm的Gunn二极管振荡器、肖特基势垒二极管制ASK调制器和环行器组成，接收端由本端LO功率10dBm的Gunn二极管振荡器和转换损耗12dB的平衡混频器组成。频率为59.75GHz的毫米波由NRD波导ASK发射机中的1Gbps时钟调制，在窄窄的大厅中间隔5mm左右的NRD波导接收机接收到的解调波向下转换为2.25GHz的中频（IF）。然后中频波被放大并被检测。通过示波器观测到的调制和解调波形在形状上是一致的，从而证实了发射信号在接收机中可以被清晰地恢复。该发射机和接收机可应用于IEEE1394系统和基于sdi的高清电视信号分配系统的无线部分。提出了一种外形简单、性能多功能的新型毫米波天线。该天线使用简单，具有从宽波束到窄波束的辐射方向图变化的显著优点。因此，可以在发射机和接收机中分别设置宽波束和窄波束天线，供基站使用和信息终端使用。少
