DR-PL-20-MOPulse Medium Output Voltage Driver Module
Driver
The DR-PL-20-MO RF drivers are amplifiers module designed to drive LiNbO3 optical modulators so as to generate undistorted optical pulses.
Electrical pulsed signals differ from classical telecom signals by long periods with no signal, when telecom signals are usually well balanced in 1 and 0. They also differ from analog signal by a wider frequency content. In order to generate clean optical pulses with sharp edges, sustained high and low levels and no overshoot, pulsed signals do require specific amplifiers.
The DR-PL-20-MO driver is optimized for low and high Pulse Repetition Frequency (PRF) signals from 10 Hz to 1 GHz. The bandwidth up to 20 GHz accommodates 50 ps narrow pulse width with short rise and fall time (down to 30 ps) and can withstand longer pulses up to 10 ns.
The DR-PL-20-MO drivers come in compact connectorized modules that match directly with iXblue modulators, they use a single voltage power supply for ease and safety of use and feature an output voltage control for maximum flexibility. An optional heat-sink is proposed as an accessory.
