Performance of TFR filters under elevated power conditions

摘要

Research into the application of thin-film piezoelectric resonator (TFR) technology in novel monolithic bandpass filtering devices is reported. Research into the performance of TFR-based filters under elevated power levels was initiated to assess the suitability of this technology in systems requiring ultraminiature transmit and transceiver functions. Characteristics of particular interest include the 1-dB compression point and the two-tone third-order intercept point. The results of research conducted on silicon-based TFR bandpass filter devices under elevated power conditions are presented.
