摘要: An acoustic-wave device with active calibration mechanism is provided. The includes at least one duplexer, a voltage-controlled oscillator (VCO), frequency discriminator and control circuit. duplexer TX filter an RX filter. resonator tunable negative impedance filter, the are disposed on same piezoelectric substrate. generates signal according to deviation of resonator. circuit connected discriminator. adjusts operating or signal.
