12 GHz Modulator Driver / RF Amplifier,  Benchtop (MD-12-B)

Data Sheet

Product Overview

The Optilab MD-12-B Modulator Driver (MD) is a 12 GHz RF Amplifier in a user-friendly benchtop that provides a high-quality, single-ended voltage to drive an external optical modulator. Typical applications include driving EML, EAM, and Mach-Zehnder devices, and it can also be used as a wideband RF amplifier with useable bandwidth of 100 kHz to 12 GHz, including its +26 dBm adjustable output, making it suitable for many RF link applications. The MD-12-B amplifies 15 Gb/s data input signals to 7.5 Vp-p drive levels, and the flat gain and group delay response yield a high quality, low-jitter electrical drive signal for digital applications. In addition to its amplification function, the MD-12-B also features a manually adjustable DC bias output voltage port, to further compliment its effectiveness when used with a standard LiNbO3 external modulator.
