HL9450 Low Pass Rise Time Filter (<1 GHz)


Datasheet PDF

HL9450 low-pass absorptive rise time filters provide superior return loss and flat group delay. This model comes in options with bandwidth up to 1 GHz (350 ps). For filters at faster speeds, please see our related model number HL9452.

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
  • 373 ps rise time, 938 MHz (opt. -373)
  • 375 ps rise time, 933 MHz (opt. -375)
  • 417 ps rise time, 840 MHz (opt. -417)
  • 439 ps rise time, 797 MHz (opt. -439)
  • 749 ps rise time, 467 MHz (opt. -749)
  • 900 ps rise time, 389 MHz (opt. -900)
  • 2.99 ns rise time, 117 MHz (opt. -2990)
  • 9.0 ns rise time, 38.9 MHz (opt. -9000)
  • 10.0 ns rise time, 35.0 MHz (opt. -10000)

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.
