HL9405 Broadband Balun (50 GHz)

This product is now available upon request with a 500 KHz bandwidth floor. Lead times may vary for this variant. Please contact HYPERLABS for details.

The HL9405 is a precision signal splitter and combiner that offers industry-leading amplitude and phase match from 5 MHz to 50 GHz at -3 dB.).

This RoHS-compliant balun is suitable for use in 40+ Gbps communications systems, high-speed analog-to-digital conversion, frequency response testing for differential devices, and many other applications.

This product is also available in 67 GHz (HL9407), 40 GHz (HL9404), and 20 GHz (HL9402) connectorized variants, as well as a PCB-mountable device (HL9403).

Technical Specifications  PDF 

  • Bandwidth (at -3 dB): 5 MHz to 50 GHz
  • Amplitude match (typical): 
    • ± 0.1 dB to 30 GHz
    • ± 0.25 dB 30-50 GHz
  • Phase match: 
    • ± 2 degrees to 20 GHz
    • ± 4 degrees to 50 GHz
  • Insertion Loss: -6 dB
  • Connectors: >2.4 mm; 1x jack input, 2x jack output
  • RoHS compliant, assembled with lead-free solder

NOTE #1: If the DC voltage of the input or output is not zero, matched DC block capacitors are required.

NOTE #2 : To achieve maximum amplitude match to 50 GHz, our baluns are designed to require a pair of highly-accurate (<1 %) 50 ohm terminations.

Product Applications

  • Changing single-ended signals to differential in high-speed analog-to-digital converters
  • Generating differential data from single-ended sources
  • Combining differential signals into single-ended while minimizing harmonic distortion
  • Pulse inversion
