SBIR Phase I: Novel Monolithic Ka to W Band Voltage Controlled Oscillators Using on Chip Varactor Integration

该小型企业创新研究第一阶段项目旨在通过将超突变变容二极管与伪形高电子迁移率晶体管(PHEMT)振荡器进行高效集成，开发新型、高集成度、高性能的高频(KA至W频段)GaAs单片压控振荡器(VCO)。这款单片微波集成电路(MMIC)将集成超突变变容二极管和PHEMT工艺所需的两个独家掺杂配置文件。这一级别的集成将简化和提高系统的整体性能，并满足可靠商业生产的成本兼容性。到目前为止，世界市场上还没有一款完全集成的高频压控振荡器产品。此外，目前可用的MMIC压控振荡器调谐范围很小(120 MHz)，相位噪声一般，不能满足当今通信系统的要求(调谐范围为500 GHz)。这项技术将把获得专利的变容二极管与毫米波VCO MMIC设计集成在一起，开发和提供一系列单片VCO，带宽超过1 GHz，100 kHz时低相位噪声为-90dBc/Hz，输出功率为16dBm，频率范围从20到94 GHz。稳定、宽调谐范围、低相位噪声、高功率、轻质、低成本的VCO MMIC是任何商业和军用无线通信系统的必不可少的组件。该项目计划开发毫米波频率的MMIC压控振荡器，以实现低成本、小尺寸、高性能的商用通信系统。该项目将满足世界各地对高频商业无线通信系统的需求，从Ka频段的本地多点分配系统(LMDS)到W频段的汽车共谋避免通信系统。此外，由此产生的产品将为国土安全系统做出贡献。

This Small Business Innovation Research Phase I project aims to develop novel, highly integrated, high performance series of high frequency (Ka to W-band) GaAs Monolithic Voltage Controlled Oscillators (VCO) by efficient integration of hyperabrupt varactor diode with the Pseudomorphic High Electron Mobility Transistor (PHEMT) oscillator. This Monolithic Microwave Integrated Circuit (MMIC) will integrate the two exclusive doping profiles needed for the hyperabrupt varactor diode and the PHEMT process. This level of integration will simplify and improve the overall system performance and meet the cost compatibility for reliable commercial production. To date, there is no product in the world market, which is a fully integrated high frequency VCO. Moreover, the MMIC VCOs available so far have very low tuning range (120 MHz) and mediocre phase noise, which does not meet the demands of present day communication systems (tuning range of 500 GHz). This technology will integrate a patented varactor diode with a millimeter wave VCO MMIC design to develop and deliver a family of single chip VCOs with over 1GHz bandwidth, low phase noise of -90dBc/Hz at 100 KHz with 16dBm output power for frequencies from 20 to 94 GHz.A stable, wide tuning range, low phase noise, high power, light weight, low cost VCO MMIC is an essential component of any commercial and military wireless communication system. This project plan is to develop MMIC VCO at millimeter wave frequencies to enable low cost, small size commercial communication systems with high performance. The project will address the needs of high frequency commercial wireless communication systems world wide, ranging from Local Multi Point Distribution Systems (LMDS) at Ka-band to Automotive collusion avoidance communication systems at W-band. In addition, resulting product will contribute to Homeland security systems.
