The microwave performance of simple microstrip structures such as gaps, bends, stubs, termination and Beatty lines was calculated using both standard RF analysis and EM analysis. The structures were manufactured on 10 mil alumina and the RF performance was measured to 60 G H z . The results are compared.The question of the accuracy of both models and measurements is always nagging, especially at higher frequencies and in non coax structures. Measurement capability for microstrip has improved dramatically in the past few years with improved test fixtures, microstrip calibration standards, dispersion correction and broadband time domain. Modeling has also improved and there are at least two major modeling techniques, standard circuit analysis, such as Touchstone, and Electromagnetic Simulation. EM can provide analysis of structures which are not currently covered by standard anal ysis .The test structures were kept simple and were mostly either broadband or were centered around 30 G H z . The structures were manufactured on 10 mil alumina which was held to a thickness tolerance of +O.OOOl".The data was gathered in DOS format and plotted through Touchstone. EM simulations were provided by Sonnet Software and EESOF. Standard analysis was by EESOF Touchstone. The RF measurements and structures were provided by Wiltron. Measurements were made on a 60 G H z Model 360 network analyzer using a Model 3680V test fixture. Calibration used microstrip standards. Due to time constraints, not all structures were analyzed by all involved.
Blind Mate Microwave connectors allow the possibility of assembling microwave subsystems like LEGGOS.' There are many versions of blind mate connectors on the market with little or no standardization. Blind mate connectors are mostly ignored by the connector standards committees. This paper will propose a method of characterizing blind mate connectors and present data on three types of blind mates to 6 0 Ghz.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
