Product description
An RF driver series with an operating frequency range from 80 – 500 MHz and output up to 8 W in RF power with a rise time as low as 4 ns. Three modulation schemes are supported: Digital, Analog and Digital + Analog.
These drivers feature the optional ability to synchronize the driver to an external clock reference and are designed to drive FiberQ modulators, frequency shifters, and acousto-optic modulators.
Key features
- Up to 500MHz center frequency
- Selectable modulation input
- Adjustable RF power up to 8 Watts
- Rise time as low as 4 ns
- Optional external clock synchronization
