The demand for broader bandwidth in data communication is continually increasing, and the integrity of RF signals has become a major design concern. In broadband bias applications, most inductors do not cover enough impedance bandwidth. Bandwidth can be increased by putting three or four inductors in series, but DC losses and filter complexity increase. A broadband bias choke can provide wide bandwidth in a single inductor package. Learn how to use broadband chokes in bias tees and critical design considerations including frequency range, DC resistance, current requirements, products size and cost.
