  • Abstract
    A novel compact high selectivity wideband differential bandpass filter with wideband common mode suppression using Marchand balun is presented in this paper. Open/shorted coupled lines and stubs are used to improve the selectivity for the differential mode and common mode suppression. The demonstrated filter with a compact size of 24 mm × 12 mm exhibits a fractional bandwidth of 53% centered at 3.0 GHz and 13 dB common-mode suppression from 0 to 9 GHz (3f0).
