Created product training courses, and provided training to customersworldwide. Oversaw the development of a mmWave radio module.

Credited by management as saving the program (and second-generation tag project), by creating an innovative circuit design that solved a major problem. This circuit was essentially a unique voltage doubler, and its function was to boost the voltage supplied by batteries in a portable RF positioning tag. It prevented a battery voltage drop from affecting an RF ASIC that could not tolerate this voltage drop. Redesigned and cost reduced a number of other system modules including a 5.8 GHz RF amplifier, 4 port RF switch, 2.4 GHz transmitter, and a number of smaller efforts. Credited with designing a very compact 2.4 GHz/5.8 GHz diplex/amplifier unit. This device was installed between successive cable runs to compensate for the losses in extended cable runs. The design included two diplex filters, 2 bias-tee’s, a 25 dB gain block at 5.8 GHz, and a 15 dB gain block at 2.4 GHz. The entire PC board measured 2.6” x .9”. Lead a team project to develop a next generation RF locating and positioning tag. Traveled to Germany to oversee the development of an RF ASIC for this device. This design is on schedule and working as intended. This design will cut the cost by over 60%, and will provide the required profit margins for this part of the system. Volunteered and taught weekly “Indoor Radio” classes to the Marketing, Sales, and SE groups.

Primary designer and project lead on the development of a 2.44 GHz ISM band Direct Sequence Spread Spectrum radio. This radio is used in an indoor wireless price labeling system. Special features included receive antenna diversity switching, and frequency agility to allow the radio to operate as a DSSS radio, or as a FHSS radio. My responsibilities included design of all circuitry, including the synthesizer and a unique DSSS modulator that utilized a PIN switch and a quad hybrid to ensure repeatable and accurate bi-phase modulation from unit to unit with no tuning necessary. Other responsibilities were to oversee the development of special patch antenna elements designed to steer the beam. All antenna work was carried out at UMass Amherst under the direction of Professor Dan Schaubert, under my requirements and direction. Worked with Graduate students making extensive antenna measurements. This radio was completed on time, with myself and one technician handling all design, prototype, layout, debug, test, FCC approvals, and introduction to manufacturing. I possess extensive experience and an intuitive ability to create circuit layouts that minimizes circuit interaction and undesired radiation. The circuit board layout was completely done by me using PADS PCB software. The radio is FCC compliant. This radio was a redesign of another attempt by an outside consulting firm. I was credited with essentially saving the company for bringing a working, manufacturable radio to market in record time. I have extensive experience designing developing and testing ISM (2.44GHz and 5.78GHz) band indoor radio gear, and I have a good knowledge of indoor radio propagation. Developed and implemented a fully functional automated production test system for this radio.
