Device Overview
General Description
The BALHE-0009SMG is a surface-mount broadband balun, hand-tuned for optimal phase and amplitude balance over 10 MHz to 9 GHz bandwidth. Designed for high volume production with cost optimization in mind, it serves as an excellent choice for analog to digital converters, balanced receivers, baseband digital modulations, and signal integrity enhancement. If lower frequency operation is required, the BALH-0009SMG offers performance down to 500 kHz in the same package.
Features
▪ 10MHz to 9GHz 1:1 Balun (Balanced to Unbalanced Transformer)
▪ Transforms 50 Ω single ended to 50 Ω differential/25 Ω single ended
▪ Tuned for Optimal Phase/Amplitude Balance
Applications
- Analog to Digital Converters
- Balanced Receivers
- Baseband Digital Modulation
- Signal Integrity

Electrical Specifications - Specifications guaranteed from -55 to +100°C, measured in a 50Ω system.
Typical Mixed Mode Performance Plots
Mixed mode scattering parameters are used to characterize differential circuits. For baluns, this means that the 0° and 180° ports become a single 100Ω differential port and the common port remains the same 50Ω common port. The two-port s-parameters of the balun are then characterized based on differential (d), common mode (c), or single-ended (s) signals. Sds21 is the differential output response given a single ended input.
