RF Microtech was asked to provide a validated full-wave electromagnetic (EM) simulation of a 2-port ultra-wideband (UWB) filter that could reject all five mobile service bands with greater than 35 dB of rejection. Furthermore, the filter had to ensure 80 MHz to 6 GHz wide-band transmission with insertion losses less than 2 dB RF Microtech’s client, H3G, also required that the device fit within a 1x1x0.2 meter enclosure, while still providing acceptable levels of coexistence to 6 GHz without signal degradation. The validated EM simulation had to be delivered within two weeks and the complete deployable device by the time the expo opened.
