20 GHz Modulator Driver with Adjustable DC Bias


The Optilab MD-20-M Modulator Driver (MD) is a 20 GHz Bandwidth RF Amplifier in a compact and user- friendly module that provides a high-quality, single-ended voltage to drive an 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 up to 20 GHz, including its +24 dBm adjustable output, making it suitable for many RF link applications. The MD-20-M amplifies 23 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.

Utilizing 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 amplification function, the MD-20-M also features a manually adjustable DC bias output voltage port, to further compliment its effectiveness when used with a standard optical modulator. The MD-20-M also supports diplexed RF + DC port configurations for full optical modulator compatibility.
