This 1:1 CT SMD balun RF transformer is designed for broadband wireless communication and RF signal conversion applications, achieving balanced/unbalanced signal conversion and impedance matching. The product uses an SMD package, offering a wide frequency range, low main-line loss, and excellent amplitude/phase balance characteristics, ensuring differential signal transmission quality. The center-tap design is suitable for circuit topologies such as push-pull amplifiers and mixers. It is widely used in VHF/UHF receivers/transmitters, antenna systems, and broadband matching networks in RF applications. It is an ideal choice for RF front-end signal conversion and matching.

FAQ
Q: What is the difference between a 1:1 CT balun transformer and a standard 1:1 balun?
A: A 1:1 CT balun has a centre tap (CT) on the secondary winding, making it suitable for circuit topologies such as push-pull amplifiers and mixers that require a centre tap, providing differential output or unbalanced-to-balanced conversion. A standard 1:1 balun does not have a centre tap and has a relatively simpler function.
Q: What does typical main-line loss of 0.4-0.5dB mean?
A: Main-line loss of 0.4-0.5dB means the signal power loss through the transformer is approximately 9-11%, indicating high energy transmission efficiency. The small difference in loss between the two outputs (0.4dB vs 0.5dB) ensures balanced differential output amplitude, suitable for RF front-ends with strict signal quality requirements.
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. Samples are free of charge and will be shipped within 3-5 working days. Mass order lead time is generally 2-8 weeks. MOQ and lead time for custom products will be confirmed separately.
