Abstract

Superconducting technology enables high-Q transmit filters for wireless base stations. However, superconducting filters are inherently nonlinear devices that cause signal distortion and spectral broadening. Third generation wireless CDMA2000 and WCDMA standards constrain the modulation accuracy and out-of-band emissions. The out-of-band emission requirements are shown to be the limiting factors that control the filter and resonator designs.
