Filters / Passives

The iFilter™ filter design utility addresses all stages and types of filter development, from lumped-element or distributed filters to more complex multiplexed, high-power, and high-Q cavity filters. Passive networks such as couplers, combiners/dividers, and attenuators are simulated with a comprehensive distributed model library to aid component designers in meeting challenging size, cost, and time-to-market goals. 


Couples seamlessly with EM solvers to simulate antenna metrics such as gain, return loss, radiation efficiency, and currents, and to visualize 2D/3D far-field antenna patterns in support of antenna design, matching-circuit development, and integration into RF front-end electronics.


Delivers superior HB circuit simulation for the multi-tone, frequency-domain analysis required by designers of mixers and frequency converters commonly found in superheterodyne receivers.
