Electrical performance of multioctave models can be optimized over narrower bandwidths for a particular parameter. Electrical options include: Lower insertion loss,
lower VSWR, higher isolation. Custom packaging also available. Examples of custom models previously shipped are shown below. Consult factory for options.

Power handling in a splitter application: 30 W CW @ load VSWR < 1.2:1, 10 W CW @ load VSWR < 2:1.
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.
