Abstract

PurposeThe purpose of this paper is to introduce modified I – Q (In–phase and Quadrature components) demodulator based on LTCC (Low Temperature Co-fired Ceramics) dielectric substrate GreenTape 951PX for M-Sequence UWB (Ultra WideBand) sensor system.Design/methodology/approachMicrostrip LP (Low Pass) and BP (Band Pass) filters for UWB sensor systems with required properties (for both filters, minimum attenuation is -40 dB in stopband, bandwidth of pass band is 6 to 8.5 GHz for BP filter and cut off frequency is 2.5 GHz for LP filter) were designed, simulated, fabricated and measured using dielectric substrates DuPont GreenTape 951 PX. The developed microstrip filters were integrated with all parts of I – Q demodulator on one multilayer structure based on LTCC substrate DuPont GreenTape 951 PX.FindingsBoth type of microstrip filters integrated in the I – Q demodulator achieved better transmission characteristics in comparison with commercial available filters. It was shown that LTCC technology based on GreenTape 951PX proves good stability in GHz frequency and suitability for fabrication I – Q demodulator with multilayer approach.Originality/valueThe novelty of this work lies in substituting commercial available LP and BP filters used in I – Q demodulator by microstrip LP and BP filters with better performance and furthermore the I – Q demodulator is fabricated based on LTCC instead of previously used PCB.
