Present work shows results obtained during an investigation of front-end part for ultra wideband (UWB) transceiver. Main topic is focused on the hardware supporting European standard that assumes the use of the total UWB frequency band with 5GHz band (4.8–6.3 GHz) cut-off. Typical realization of the front-end part uses single full-band antenna, bandpass filter (BPF) and bandstop filter (BSF). The...
Cascaded filters offer a possibility to minimize the size of the filter components due to their increased attenuation at high frequencies. A cost optimized design of a cascaded filter of a multi-phase converter for an automotive energy backup system will be shown, that results in small values of the inductances. However, the decreasing inductance values results in increasing current ripples in the...
