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. Benchtop wideband vector measurement of millimeter-wave components and networks is desirable for rapid evaluation and evolution of bridge designs in our HF spectrometers. However, no relatively low-cost system of this type presently exists for millimeter-wavelength studies at W-band and higher. Therefore, we have designed a new type of versatile swept vector/magnitude-response evaluation set and contemplate assembling this instrument in a form usable over the millimeter-frequency ranges of our sources at 95, 170, 240 and 250GHz. Our preliminary design is a straightforward, effective and relatively inexpensive approach to such measurements, and, for economy, is based the use of several instruments and components presently on hand at our Center. For each millimeter-wave band, we propose to combine a conventional vector network analyzer (or spectrum analyzer for vector magnitude-only studies) and its companion tracking generator with a appropriate phase-locked source, and, with a waveguide harmonic mixer, PLDRO and several standard microwave components, realize an economical but high-performance scalar network analyzer. Our design is unique in that it is based on and offers the performance advantages of a cost-effective, high-dynamic range block converter, in this case combined with a millimeter-wave source which is phase-locked to the conventional vector network analyzer (or spectrum analyzer/tracking generator). This pairing allows us to realize an instrument of exceptional capability through the higher millimeter-wave frequency bands. We will only need to construct a fast divider (or, alternatively, substitute a frequency-specific PLDRO) and the mixer sections, since all other sub-systems are, or will be, on hand. Specifications at 170GHz are: sweep span of 10.0GHz and a dynamic range of 75dB for 20KHz resolution. Other millimeter-wave bands are to be addressed by substitution of appropriate source modules and waveguide-harmonic-mixers. Construction of a swept millimeter-wave analyzer based on this new design will be initiated during the ensuing Center grant renewal period.

该副本是利用资源的众多研究子项目之一 由NIH/NCRR资助的中心赠款提供。对该子弹的主要支持 而且，副投影的主要研究员可能是其他来源提供的 包括其他NIH来源。 列出的总费用可能 代表subproject使用的中心基础架构的估计量， NCRR赠款不直接向子弹或副本人员提供的直接资金。 台式宽带矢量测量毫米波组件和网络对于我们的HF光谱仪中的桥梁设计的快速评估和演变是可取的。但是，目前，对于W波段和更高的毫米波长研究，目前尚无这种类型的相对低成本系统。因此，我们已经设计了一种新型的多功能扫描媒介/幅度响应评估集，并以95、170、240和250GHz的毫米频率范围的形式集合此仪器。我们的初步设计是一种直接，有效且相对便宜的方法来进行此类测量，而对于经济来说，基于目前在我们中心的几种仪器和组件的使用。对于每个毫米波频段，我们建议将传统的矢量网络分析仪（或仅用于矢量幅度研究的频谱分析器）及其伴随跟踪生成器与适当的相锁定源组合，并使用波导指导谐波混合器，PLDRO，PLDRO，PLDRO，PLDRO和几种标准的微波构件，实现经济但高强度的标准量量表分析仪。 我们的设计是独一无二的，因为它基于并提供了具有成本效益的高动力范围转换器的性能优势，在这种情况下，与传统的矢量网络分析仪（或Spectrum/Tracking Inerager/Tracking Ineratiat机构）相结合，并结合了毫米波源。这种配对使我们能够通过较高的毫米波频带实现具有出色能力的工具。 我们只需要构建一个快速的分隔线（或者替换频率特定的PLDRO）和混音器部分，因为所有其他子系统都是或将在手上。 170GHz的规格为：10.0GHz的扫描跨度和20kHz分辨率的75dB的动态范围。其他毫米波频带应通过替换适当的源模块和波导谐波混合物来解决。基于此新设计的扫描毫米波分析仪的建设将在随后的中心赠款续期期间启动。
