Capacitors in Broadband Applications
Abstract:
Proper selection of capacitors for RF broadband applications requires careful evaluation of frequency dependent parameters and certain design requirements. In today’s rapidly expanding RF and microwave markets, numerous designs must operate over multiple octaves of frequency spectrum. Some of the more common of these include broadband bias networks such as transistor emitter and FET source bypassing, transistor collector and FET drain feed structures, as well as interstage RF coupling, DC blocking, and wideband impedance matching.
