Abstract: With the advent of the increased bandwidth for support of 5G infrastructure there a growing need for testing of active components at 60 GHz. In this presentation I will review some of the drivers for this increased bandwidth and cover the types of measurements and how these are addressed using an application based measurement architecture. In addition we will look at the enabling technology in terms of the hardware and software features for calibration. In addition the paper will focus on a single connection multiple input measurement of a typical transmitter receiver used in the 60 GHz band for 5 GHz backhaul systems
Biography: Suren Singh is a microwave, millimeter wave, and Terahertz metrology application specialist based in Santa Rosa, California. Suren works with industry leaders around the world to help them address a wide range of millimeter wave measurement challenges. Suren has been with the Hewlett-Packard Company and now Keysight Technologies since 1986. His experience at Keysight includes application engineering, product design, manufacturing and test process development for microwave hybrid microcircuits. He currently holds the position of an application specialist business manager focused on the microwave, millimeter wave, and Terahertz measurement solutions. In addition, he is responsible for the metrology products for performance network analyzers, including both calibration and verification. He received his BSEE from University of Durban-Westville, Durban South Africa in 1985. He completed a Graduate Diploma at the University of Witwatersrand, Johannesburg South Africa in December 1992. He then went on to complete his MSEE at the University of Witwatersrand, Johannesburg in 1995.

"Terahertz Radar and its Capabilities for Stand-Off Imaging"
Abstract: The frequency spectrum above 50 GHz has seen increased interest recently from commercial, defense, and security sectors. The unlicensed 71-76 GHz and 81-86 GHz bands offer opportunities for short-range very high date rate wireless channels. Automotive radar continues to develop systems at 77 GHz and 120 GHz. Significant bandwidth is also available in the atmospheric windows around 240 GHz and researchers are working on chipsets, antenna, and subsystems to exploit these frequencies. To develop components and systems at these higher frequencies, precision measurement equipment is required to characterize performance. Compact Mini Vector Network Analyzer (VNA) frequency extension modules have been developed by VDI for all frequency bands from WR-15 though WR-3.4 (50 to 330 GHz), with prototypes in development for higher bands. The volume has been reduced to 25% the volume of the standard size modules while maintaining test port power above +6 dBm up through WR-10 and 0 dBm through WR-5.1, dynamic range above 120 dB, and excellent stability.These modules are available in both Mini transmit-receive (TxRx) for full two-port S-parameter measurements and smaller Micro receive-only (Rx) configurations. In this talk, we will describe the capabilities and use of these extender modules.
Biography: Dr. Eric W. Bryerton received his BSEE from the University of Illinois in Urbana-Champaign and his PhD in EE from the University of Colorado at Boulder. From 1999-2013, he was a research engineer at the National Radio Astronomy Observatory (NRAO) where he was responsible for the design, development, and construction of the 30-950 GHz local oscillator system for ALMA (Atacama Large Millimeter Array), an array consisting of 66 twelve-meter antennas with nearly quantum-noise limited cryogenic SIS receivers located on the Atacama plateau in northern Chile. While at the NRAO, he also developed cryogenic W-band MMIC low-noise amplifiers and SIS receivers up to 1 THz. Before joining VDI in the Fall of 2013, he was the Deputy Assistant Director for the NRAO R&D laboratory, helping to oversee the development of radio astronomy instrumentation from the radio through THz. Since joining VDI, Eric is enjoying applying the development of highly integrated sub-millimeter and THz modules to many other research areas besides radio astronomy, including sub-millimeter test equipment extender modules, CubeSat atmospheric studies, ITER plasma diagnostics, and high-data-rate millimeter-wave communications.
