HL9404 Broadband Balun (40 GHz)

Effective 10/15/17, bandwidth (-3 dB) is now extended down to 500 kHz.

The HL9404 is a signal splitter and combiner that offers industry-leading amplitude and phase match from 500 kHz to 40 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 is a high-performance version of HYPERLABS' best-selling HL9402 balun and the PCB-mountable HL9403. A 50 GHz version of this product is available as the HL9405 and the new HL9407 offers 67 GHz bandwidth.

Technical Specifications

Bandwidth (at -3 dB): 500 kHz to 40 GHz
Amplitude match:

± 0.1 dB to 20 GHz
± 0.25 dB 20-40 GHz

Phase match:

± 4-6 degrees at 20 GHz, typical
± 8-12 degrees at 40 GHz, typical

Insertion Loss: -6 dB
Connectors: 2.92 mm (K); 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 40 GHz, our baluns are designed to require a pair of highly-accurate (<1 %) 50 ohm terminations.
