HL9450 Transition Time Converter (<1 GHz)


Datasheet  | S-parameters

HL9450 transition time converters (also known as low-pass absorptive rise time filters) provide superior return loss and flat group delay. This model comes in options with bandwidth below 1 GHz (350 ps). For filters at faster speeds, please see our relegated models in the HL945x Series.

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.

Key Specifications (typical)
Rise Time (10-90%) 373 ps to 9 ns, depending on option
Bandwidth (3 dB) 38.9 to 938 MHz, depending on option
Group Delay (3 fc) 510 ps to 8.15 ns, depending on option
Max Input Power +25 dBm
Connectors SMA, 1x jack, 1x plug
ROHS compliance Yes, assembled with lead-free solder
Warranty 1 year, repair or replacement
