Transition Time Converters

The HL945x  family of transition time converters (also known as low-pass absorptive rise time filters) provide superior return loss and flat group delay.

Designed using HYPERLABS’ proprietary absorptive filtering, these filters offer similar frequency response as 4th order Bessel-Thompson filters.

These filters are suitable for OEM use in high-speed telecom and digital networks, as anti-aliasing filters in digital oscilloscopes, and to limit the RF bandwidth to known values.

Model HL9450 can be built to any frequency up below 1 GHz (350 ps rise time).

The HL9452 is available at frequencies from 1 GHz (350 ps) to 15 GHz (23 ps).

For faster systems, the HL9454 is available at frequencies up to 28 GHz (12.5 ps).

At the top of our product line, the HL9457 is available at frequencies up to 50 GHz (7 ps).

Upon request, HYPERLABS can also design even faster TTCs to 50+ GHz.  For more information about this service, contact us.

In addition to the options listed within this website and datasheet, HYPERLABS offers customers quick-turn custom filter designs up to 50+ GHz.

The full-turn service includes design, manufacturing, and assembly. Small quantities are typically available within a few weeks.

Please contact us for more information about these custom designs.
