Electrical performance of multioctave models can be optimized over narrower bandwidths, or for a particular parameter. Electrical options include: Lower
insertion loss, lower VSWR, higher isolation, flat amplitude response, amplitude tracking. Mechanical/Control options include: Custom packaging, single
supply operation, fast switching time, single TTL control line. Examples of custom models previously shipped are shown below. Consult factory for options.

*For reflective models, VSWR is not specified in the “OFF” state.
For absorptive models, VSWR in the “OFF” state is defined for port J2 only.
