50 GHz Modulator Driver/RF Amplifier (MD-50)

Data Sheet

Product Overview

The Optilab MD-50 Modulator Driver (MD) is a 50 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 wide band RF amplifier with useable bandwidth of up to 50 GHz. MD-50 amplifies 60 Gb/s 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. The RF gain and eye crossing level can be easily adjusted using the knobs on front panel or remotely from the USB interface. It also integrates a LCD display to show status information. Featuring a single 12V DC control and a built in heat sink, this versatile module also has an anodized, precision-machined aluminum housing designed for efficient heat dissipation during prolonged use. In addition to its amplification function the MD-50 also features a manually adjustable DC bias output voltage port, to further complement its effectiveness when used with a standard LiNbO3 modulator.
