WebDesigned for those who want the maximum isolation and choking across the full HF spectrum. Building on the original 1:1 design by Dr. Jerry Sevick, this balun has two (2) cores in a stacked configuration to maximize choking impedance on HF bands from 1- 54MHz.
WebJun 3, 2024 · Abstract: This brief presents a high-power Sub-6 GHz two-way differential power amplifier (PA) with a series distributed-balun output network in $0.5{\mu }\text{m}$ GaAs pHEMT process. The proposed series distributed-balun output network consists of two coupled-line-based distributed-baluns connected in series to achieve low-loss … WebBecause it is a current controlling device and not a transformer, there can be no such thing as a 4:1 current balun. Put another way, a current balun controls currents presenting a low impedance, through the device, to desired currents but a high impedance to unwanted ones.

WebThe voltage balun always dumped some of the power somewhere else. The picture below shows a thermal image if a 1:1 current balun with only one of the output ports connected to a load. No current flows into the load so a large proportion of the RF power is dissipated in the balun core. Note that the actual windings remain quite cool in comparison.
