| High Light | SMD Balun 75Ω for VHF/UHF ，5-3000MHz RF Transformer ，SMD Balun for transmitters receivers | ||
This SMD balun RF transformer uses enamelled copper wire winding and a surface-mount package. Impedance ratio is 1:1, characteristic impedance is 75Ω, and frequency range is 5-3000MHz. RF power: 0.25W. DC current: 30mA. A balun transformer is used for balanced-to-unbalanced signal conversion, converting balanced signals (differential signals) to unbalanced signals (single-ended signals), or vice versa. It is widely used in broadband wireless communication, VHF/UHF receivers/transmitters, and push-pull amplifiers in RF circuits.

Q: What is the main function of a balun transformer?
A: A balun transformer is used for balanced-to-unbalanced conversion, converting balanced signals (differential signals) to unbalanced signals (single-ended signals), or vice versa. It is widely used in RF circuits, mixers, antenna feeding, and broadband matching networks.
Q: What does a 1:1 impedance ratio mean?
A: A 1:1 impedance ratio means the primary and secondary impedances are equal (both 75Ω). It does not perform impedance transformation, but only provides balanced-to-unbalanced signal conversion. It is suitable for RF circuits that require balun conversion without impedance transformation.
Q: How to apply for samples? What is the lead time?
A: You can submit a sample application through our website or email. Please provide your company information and target model (including frequency and impedance requirements). Samples are free of charge and will be shipped within 3-5 working days. Mass order lead time is generally 2-8 weeks.
