HL9403 Broadband SMT Balun (20 GHz)

The HL9403 is a drop-in / surface mount (SMT) broadband balun with typical ± 0.25 dB amplitude match from 5 MHz to 20 GHz (-3 dB) and ± 2 degree phase match typical at 10 GHz.

This product is optimized for use in high-speed analog-to-digital conversion, differential signal generation, harmonic distortion minimization, and pulse inversion.

The HL9403 is designed to be installed onto printed circuit boards, offering unmatched on-board performance for aerospace, R&D, and other cutting-edge applications.

An SMA connector version of this balun is available as the HL9402, while the HL9404 offers an extended 40 GHz bandwidth.

Technical Specifications  PDF

  • Bandwidth (-3 dB): 5 MHz to 20 GHz
  • Amplitude match: ± 0.25 dB, typical
  • Phase match: ± 2 degrees, typical at 10 GHz
  • Insertion Loss: -6 dB
  • Mounting configuration: 3 leads to be soldered to PCB traces, 4 1-72 mounting screws (included)

NOTE #1: DC block capacitors are required if the DC voltage of the input or output is not zero. To maintain the full performance of the balun, amplitude- and phase-matched block capacitors should be used.

NOTE #2: To achieve maximum amplitude match to 20 GHz, our baluns are designed to require a pair of highly-accurate (<1 %) 50 ohm terminations.
