DR-DG-10-HO

12 Gbps High Output Voltage Driver Module

Photline Driver

The DR-DG-10-HO is a driver module optimized for digital applications requiring
an upper operation voltage at 12.5 Gbps. It exhibits 12.5 Vpp output voltage and35 dB gain up to 7 GHz.
The DR-DG-10-HO module is especially useful for driving LiNb03 modulatorswith 12 Gbps DPSK and 2 x 12 Gbps (D)QPSK modulation formats.

FEATURES

It is also a key device for multi-level modulation formats and for driving
phase modulators. It is operated from a single power supply voltage forsafety and ease of use and offers output voltage control. The DR-DG-10HO comes with SMA type RF connectors (female in, male out) and with
an optionnal heat sink. It is a non-inverting and single ended amplifier.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional
operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of the data sheet. Exposure
to absolute maximum ratings for extended periods can adversely affect device reliability.
