Sirenza Microdevices Inc., a designer and supplier of RF components, has been granted U.S. patent number 6,480,067, entitled "Peaking Control for Wideband Laser Driver Applications."

The new patent applies to a unique method of shaping or equalizing a high-data-rate output-signal waveform of wideband amplifiers used in fiber-optic transmitter applications. It is one of a number of pending patents filed by SMDI to protect its innovative fiber-optic component design solutions.

"The effectiveness of existing peaking techniques can be marginal at 10Gbps and higher due to the quality of the raw data signal which provides a clock, or trigger, for the technique," Kevin Kobayashi, director of advanced design for Sirenza, and co-inventor of the newly patented method, elaborated. "The analog peaking technique covered by this patent does not rely on the raw data waveform as a clock or synchronizing signal for the technique to be effective, and is therefore more suitable for higher data-rate applications."
