Low Pass Rise Time Filters

The HL945x  family of 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.

Available options for Model # HL9450:

  • 60 ps rise time, 5.83 GHz (Opt. -60)
  • 100 ps rise time, 3.5 GHz (Opt. -100)
  • 150 ps rise time, 2.33 GHz (Opt. -150)
  • 200 ps rise time, 1.75 GHz (Opt. -200)


In addition to the options listed within this website and datasheet, HYPERLABS offers customers quick-turn custom filter designs up to 45 GHz.

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