Quad 40 GHz Modulator Driver/RF Amplifier (MD-40-X4-R)

Data Sheet

Product Overview

The MD-40-X4-R is a quad channel, 40 GHz Bandwidth RF Amplifier, enclosed in a single 1U rackmount housing.  Each channel on the MD-40-X4-R provides a high-quality, single-ended voltage to drive an external LiNbO3 modulator, with independent control and monitoring on all amplified signals. Typical applications include driving EML, EAM, and Mach-Zehnder modulators, and amplifies 50 Gb/s data input signals to >7.5 Vp-p drive levels. The MD-40-X4-R flat gain and flat group delay response yields a high-quality, low-jitter electrical drive signal, that can also be used as a wideband RF amplifier with useful bandwidth of up to 40 GHz. Its high gain of 27 dB makes it suitable for many RF link applications, and is a perfect match to Optilab’s extensive optical transmitter catalog, with remote accessibility via a single USB port.
