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赝晶高电子迁移率晶体管（PHEMT）振荡器有效集成，开发新型、高度集成、高性能系列的高频（Ka至W波段）GaAs单片压控振荡器（VCO）。 这种单片微波集成电路（MMIC）将集成超突变变容二极管和PHEMT工艺所需的两种独特的掺杂分布。这种集成水平将简化和提高整个系统的性能，并满足可靠的商业生产的成本兼容性。 迄今为止，世界市场上还没有一种产品是完全集成的高频VCO。此外，迄今可用的MMIC VCO具有非常低的调谐范围（120 MHz）和中等的相位噪声，这不满足当今通信系统的需求（500 GHz的调谐范围）。该技术将专利变容二极管与毫米波VCO MMIC设计集成，开发并提供一系列单芯片VCO，其带宽超过1GHz，在100 KHz时相位噪声为-90dBc/Hz，在20至94 GHz频率下输出功率为16 dBm。低成本VCOMMIC是任何商用和军用无线通信系统的基本组件。本计画主要是开发毫米波频率的MMIC压控振荡器，以实现低成本、小尺寸、高效能的商用通讯系统。该项目将满足全球高频商用无线通信系统的需求，从Ka波段的本地多点分配系统（LMDS）到W波段的汽车避免共谋通信系统。此外，由此产生的产品将有助于国土安全系统。

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.
