项目摘要
This subproject is one of many research subprojects utilizing the resources
provided by a Center grant funded by NIH/NCRR. Primary support for the subproject
and the subproject's principal investigator may have been provided by other sources,
including other NIH sources. The Total Cost listed for the subproject likely
represents the estimated amount of Center infrastructure utilized by the subproject,
not direct funding provided by the NCRR grant to the subproject or subproject staff.
We succeeded in the design of both homodyne and heterodyne 35 GHz pulsed microwave bridges. The heterodyne bridge of our design is intended for work in conjunction with a high-power TWTA and can be tailored for work with a several watt solid-state amplifier, i.e. for the project on protein folding, wherein solid-state power amplifier option is in our research plans. We will use a number of inexpensive MMIC working at C or X band IF in the heterodyne bridge. The schemes at different levels of complexity are in place, with the least expensive ones also being well-suited for 3D EM. The bridge electronics will be integrated with low-end timing systems based on home enhanced SpinCore Pulse Bluster card and Acqiris averager, or else can be integrated with the high-end timing systems (working with Acqiris or home-built averagers), which were methodically developed in several subprojects related to pulse and FT ESR.

我们成功地设计了零差式和外差式35 GHz脉冲微波桥。我们设计的外差电桥旨在与高功率行波管一起工作,并且可以为几瓦的固态放大器工作而量身定做,例如,用于蛋白质折叠项目,其中固态功率放大器选项在我们的研究计划中。我们将使用一些廉价的MMIC工作在C或X波段,如果是在外差电桥上。不同复杂程度的方案已经到位,最便宜的方案也非常适合3D EM。桥梁电子设备将与基于家用增强型SpinCore Pulse Blaster卡和Acqiris Averager的低端计时系统集成,或者也可以与高端计时系统(与Acqiris或自制均衡器一起工作)集成,这些系统是在与Pulse和FT ESR相关的几个子项目中有条不紊地开发的。
