SMD Balun / Wideband Transformers
Surface mount wideband RF transformers
The basic functions of SMD balun are to suppress the common mode current, impedance conversion (with different impedance ratios), and covert voltage or current from unbalanced to balanced. Coilmaster Electronics produces various kinds of SMD common-mode RF transformers (balun transformers) which are used to convert between unbalanced-balanced signals in the antenna inputs of tuner circuits for terrestrial digital broadcast compatible compact devices. Windings use paired or triple wires for high uniformity.
On the surface mount wideband RF balun, Coilmaster also utilizes the latest winding technology using paired wires for high uniformity and enabling the most cost-effective designs in manufacturing common mode choke, RF balun transformer products. Ideal for use in double balanced mixers, as broadband transformers, transistors, and for impedance conversion.
SMD choke coils, and common mode choke SRIDB series (RF Balun Transformer) series are pair wire coils for high stability and high common-mode impedance. It is effective at suppressing common mode noise in digital equipment where radiation is caused by cables. Custom Balun Transformer is also available for us.
