BROADBAND POWER DIVIDERS
FEATURES
Multioctave bands
Microstrip construction
Low loss
High isolation
Small size
MITEQ offers a broad range of Wilkinson-type power dividers covering multioctave bands from 2 to 18 GHz, and
custom power dividers up to 40 GHz are also available. Power dividers up to 16-way are available as standard
products. These products feature excellent amplitude, phase balance and lowest possible loss. We can provide
these components as drop-in functions for those applications that require higher levels of integration. We offer MIL-
STD-883 screening and custom connector options.
