Agilent Technologies Introduces Industry's Smallest Hermetically Sealed Surface Mount Optical Driver Amplifier

11/21/2002 - Agilent Technologies introduced the industry's smallest hermetically sealed surface mount optical driver amplifier specifically designed for use in OC-192/STM-64 10 Gb/s SONET/SDH fiber optic communication systems. The Agilent MDA-1220-08S is also the industry's first surface mount modulator driver amplifier to provide radio frequency (RF) shielding in a hermetically sealed small form factor package, and offers network equipment manufacturers (NEMs) ease of integration and reduced costs.

"Agilent's hermetically sealed, RF shielded package ensures that the SONET/SDH system will be reliable and will meet mandated electromagnetic interference specifications," said Bryan Ingram, vice president and general manager of Agilent's Wireless Semiconductor Division. "Our significant size advantage, increased reliability and excellent EMI performance enable our customers to reduce the cost of manufacturing new fiber optic systems."

Optical modulator driver amplifiers convert low-level electrical data into sufficient power levels to drive optical modulators without adding signal distortion. Traditionally, hermetic modulator drivers have been supplied in a metal housing with SMA connectors on both ends and a connector for mounting the driver to the board. The Agilent MDA-1220-08S is supplied in a 17.247 mm by 11.354 mm by 4.318 mm (0.679 inches by 0.447 inches by 0.170 inches) hermetic surface mount package, which is up to 80 percent smaller than the traditional hermetic metal housing.

The Agilent MDA-1220-08S can be used in OC-192/STM-64 communication system applications with or without forward-error correction (FEC) protocols. The amplifier offers wide bandwidth operation of 30 kHz to 15 GHz. Using advanced GaAs technology, it will drive both electro-absorption (EA) and lithium niobate (LiNbO3) Mach-Zehnder electro-optic modulators. This amplifier is designed for use between multiplexer (MUX) chips and the modulator to amplify non-return to zero (NRZ) or return-to-zero (RZ) signals from 9.953 Gb/s to 12.5 Gb/s.

Its standard performance characteristics include 20 dB typical gain, an output voltage of up to 7.5V peak-to-peak into a 50 ohm optical modulator load, 15 ps rise time, and +/- 1.5 dB gain ripple. The amplifier provides both crossover point and output power control for maximum design flexibility.

U.S. Pricing and Availability
The Agilent MDA-1220-08S driver amplifier is currently sampling to select NEMs. General availability is planned for second quarter 2003, with device pricing expected to be under $500 each in high volume. To meet specific customer requirements, higher gain and output power level versions are available on request.
