Sirenza obtains patent for fiber-optic transmitters

Sirenza Microdevices has received an U.S. patent number 6,750,717 entitled "Peaking Control for Wideband Laser Driver Applications." The patent is one of several awarded to Sirenza in the area of broadband amplifier ICs and discloses an approach for equalizing the wideband performance of a fiber-optic transmitter intended for high data rate communications.

"At high data rates, direct modulated fiber-optic transmitter applications typically experience signal distortion due to laser diode nonlinearity; consequently low cost packaging is often problematic. This patent provides an electronic means that can restore signal clarity in these applications," stated Kevin Kobayashi, senior director of advanced design. "Because of the electronic or IC-based nature of this patent, it may be applicable to other wideband systems such as instrumentation and cable distribution applications," added Kobayashi.
