12 GHz Modulator Driver w/ Adjustable DC Bias (MD-12-DC)

Data Sheet

Product Overview

The Optilab MD-12-DC Modulator Driver (MD) is a 12 GHz Bandwidth RF Amplifier in a compact and user-friendly module that provides a high-quality, single-ended voltage to drive an external LiNbO3 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 up to 12 GHz, including its +26 dBm adjustable output, making it suitable for many RF link applications. The MD-12-DC amplifies 12.5 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. Featuring a 12 V DC power supply, this versatile module also has an anodized, precision-machined aluminum housing designed for efficient heat dissipation during prolonged use.  In addition to its amplfication function, the MD-12-DC also features a manually adjustable DC bias output voltage port, to further compliment its effectiveness when used with a standard LiNbO3 external modulator.
