Abstract

This letter reports on the performances of a frequency-tunable lead-zirconate-titanate-transduced fully differential mechanically coupled high-overtone width-extensional filter. The demonstrated electric field tuning provides channel agility and bandwidth adjustability for the incorporation of analog spectral processors in modern radio receiver architectures. We designed and experimentally characterized the higher overtone frequency response of a fully differential width-extensional filter. The filter demonstrates a center frequency (f_C) tuning range of 7 MHz at 260 MHz and an adjustable bandwidth from 3 to 6.3 MHz while maintaining a maximum frequency shift due to hysteresis effects below 0.14% and a stopband rejection floor of -60 dB.
