Product family: VWA-15-VA-257
5 Gb/s, 10,7 Gb/s RZ & 12,5 Gb/s NRZ
Driver Amplifier with 6 to 8 Vpp Output controlfor LiNbO3 (LN)
and Electro Absorption (EA) Modulators

DescriptionFeatures

The VWA-15-VA-257 is a broadband dual stage GaAs MMIC
amplifier module, which provides up to 25 dB gain from 55 kHz
to 15 GHz and delivers +21 dBm of output power, with a single
Voltage regulated Bias. The output voltage can be set between 4to 8 Vpp in varying the Pin V ctl.

Very Low Jitter
Very Low rise and fall time (bellow 17ps)
Output Vpp control
Ultra Wideband
Very High Gain
Medium power50 Ohm impedanceSingle +12V supplyApplications
Main applications include: Long Haul, Medium Haul, MetroAccess, Test Bench, Test & Measurement.
This unit performs LN and EAM driver functions for 10.7 Gb/s RZ
data rates and 2.5 Gb/s, 5 Gb/s, 9,958 Gb/s and from 10,7 Gb/s
to 12.5 Gb/s for NRZ data rates. The driver amplifier has singleended input and output, and SMA field replaceable RFconnectors (male or female

Handling

This product is sensitive to electrostatic discharge andshould not be handled except at a static freeworkstation. Take precautions to prevent ESD; usewrist straps, grounded work surfaces and recognizedanti-statictechniques
whenhandling
theVWA-15-VA-257 module.

Care should be taken to avoid supply transient and overvoltage. Over voltage above the maximum specified inabsolute maximum rating section may cause permanent
damage to the device.
