Senior Microwave Design Engineer
Bruce Bosco received his B.S. and M.S. in Electrical Engineering from Arizona State University.
rom 1987 through 1990, Bruce worked as a Microwave Design Engineer at M/A-COM Active Assemblies Division (now Crane Technologies) in Chandler, Arizona. Projects and design activities included medium power and low noise amplifiers. Further, he began working on improving the reliability and manufacturability/repeatability of dielectric resonator oscillators (DROs), more specifically, voltage tunable/phase lockable DROs. To support this work, he developed a preliminary MATCAD-based design algorithm that provided a means of evaluating tradeoffs between output power, phase noise and tuning range of the DRO’s. Bruce also worked as a research assistant in the area of ultra low-loss, pin diode switches. He also served as project lead on several key programs. Note that all of the these modules/subsystems were for military/aerospace applications and were therefore hybrid, hermetically sealed technologies.
From 1990 through 1994, Bruce was involved in the emerging RF Identification (RFID) field with Amtech Systems Corporation in Albuquerque, NM. Design work included synthesizers, modulators, detectors, switches and other similar networks. Some notable work included the introduction and incorporation of surface mount filters and other emerging technologies that would lead ultimately to lower cost manufacturing costs, including greatly reduced tuning and alignment time by the RF Technicians. Bruce also developed a unique planar radial combining structure that was implemented to combine several low cost, plastic packaged FETs into a power amplifier of about 1W. Finally, Bruce furthered his oscillator experience in the development of a ultra-low phase noise, electromechanical tunable cavity oscillator
From 1994 through 1998 Bruce worked as a Senior Microwave Design Engineer at Comtech EF Data, in Tempe, AZ. Here he served as project lead for several key microwave projects in the area of earth terminals for satellite communication applications. Focus was on high performance wireless product design and development with emphasis on low-cost manufacturing, reliability, and a highly transparent solution for the end-use customer. Circuits included amplifiers, oscillators (DROs, cavity and lumped element), filters, and other high frequency circuits. Integrated subsystem designs included synthesizers, up and down converters, and phase locked frequency converters. Frequencies involved ranged from 6 through 18 GHz. Further, Bruce was extensively involved in mechanical conceptual design, cost analysis, and test planning.
From 1998 through 2001 Bruce was employed by Motorola Satcom Division, Tempe, AZ, where he was a Senior Member of the Technical Staff. His role including lead designer for numerous MMIC and hybrid designs. He was a contributor for foundry interface and evaluation and device model extraction. Bruce led multiple, complex, next generation projects include MMICs operating from 2.5 to 60+ GHz. Designs included power and low noise amplifiers, frequency multipliers, mixers and other active and passive circuits. Bruce formulated a novel approach to implement a 60 GHz MMIC VCO with on-chip resonator and voltage tuning option. Design met all design specifications through careful analysis, simulation and design and was one of the first MMIC VCOs to be demonstrated at this frequency. Finally, Bruce directed the design of a 24 to 33 GHz low noise MMIC amplifier with excellent noise/gain performance, and highest linearity of any known commercially available competitive device. Chip size was 50% smaller than competing available devices at the time.
From 2001 through 2009, Bruce was with Motorola Corporate Labs, also in Tempe, AZ. His interests included the design and development of commercially viable, very high data rate systems and networks. During this period, Bruce was involved in R&D activity at Gigabit data rates, primarily over WLANs but also including WPANs and point-to-point backhaul applications. Further, he directed system architecture conception, simulation and design including packaging and antennas. This work cumulated in leading a cross-functional team that produced a low cost multi-gigabit point to point wireless system utilizing the newly released, unlicensed 60 GHz band. Bruce was also involved in other R&D work including low cost, high performance packaging solutions, participation in IEEE 802.15.3c – high rate PHY using the 60 GHz band, FMCW radar protypes at 60 and 77 GHz and millimeter wave imaging at 94 GHz.
From 2009 through 2015, Bruce returned to Comtech EFData, in Tempe, AZ, where he served as a Staff Scientist. His primary role was to develop a line of Ka band transceivers for SATCOM applications. Projects included up and down block converters and LNAs. Bruce was also involved with Ka band power amplifier PA design work including linearization and power MMIC procurement and evaluation.
From 2015 through 2019, Bruce worked at Raytheon Missile Systems in Tucson, AZ. Bruce served as the “Responsible Engineering Authority” (REA) on several key developmental programs. Most of this work was performed at module or sub-module level. Functions included synthesized sources, IF converters, GPS antenna modules and so on. End-use for most development work was for missile guidance systems and support systems. Other focus of work was on redesign of various modules to update designs and remove obsolete components. Frequencies ranged from ~ 1 GHz to 12 GHz.
From late 2019 through Present, Bruce has been involved in consulting and contract work. Work to the present point has been focused around designs involving extensive EM simulation, for example, combiner networks, filters and compact planar antennas. His present interests include advanced simulation techniques, advanced architectures and leveraging his extensive experience to provide reduced cost, manufacturable high end electronic solutions.
