The following summary was developed from material
supplied by Elaine Ollendorf
in Jan 2001.
Ollendorf held a variety of postions at RCA in the Solid State Division
during this time. He was the
engineering leader responsible for power transistor development for
consumer electronics applications.
He directed development of numerous industry firsts, such as first
power output transistor suitable for high fidelity audio applications,
first successful TV horizontal deflection transistor, first high voltage
audio output for operation at line voltage. The products developed in this period generated many millions
of dollars in margin.
1968-1972: Joel left RCA during this time to
become a Cofounder and VP for Powertech Inc. in Clifton, NJ. He designed very large silicon power
transistors and Darlington arrays with switching capability up to 1200 amps
at 80v. The company was successful
both technically and commercially.
