Narrow band, high power ceramic tongue loads are designed for a 20% bandwidth with typically 1.1:1 VSWR or less. Available in sizes from WR62 through WR284, these loads provide a large surface contact area for good heat transfer. Ceramic tongue insert loads can be supplied with mounting options to fit every need.
