Datasheet | S-parameters | Footprint | STEP File
The HL9491 is a surface mountable (SMD) signal splitter and combiner that offers excellent amplitude and phase match over an industry-best bandwidth of 1 MHz to 20 GHz (3 dB).
This ROHS-compliant product is optimized for use in high-speed analog-to-digital conversion, differential signal generation, harmonic distortion minimization, and pulse inversion.
For other high-performance balun products, please see our complete line of ultra-broadband baluns.

NOTE #1: If the DC voltage of the balanced or unbalanced ports is non-zero, DC blocks are required. The balanced ports (2 and 3) are DC shorted..
NOTE #2: To achieve maximum amplitude match to the specified frequency, our baluns are designed to require highly-accurate (< 1%) 50 Ω terminations on the differential outputs.
