About the Owner

Jeffrey Pawlan began studying electronics at age 12, and has been a licensed amateur radio operator since 1960. After graduating UCLA where he studied engineering, chemistry, physics, and music, he began his career in electronic engineering. He has worked for a number of prominent companies in both Northern and Southern California on a permanent or consulting basis and became a full-time independent consultant in 1990.

In 1990 he founded Pawlan Communications to provide independent consulting services to large and small companies all over the United States. In this capacity, he has designed many wireless LANs, RFID tag systems, and handheld products. Currently, his favorite research areas are low noise wide dynamic range amplifiers, low phase noise oscillators, and Software Defined Radios.
