A shunt-capacitance-type ladder-type topology was proposed by adding a shunt capacitance in a ladder-type topology to further reduce the insertion loss of a narrow-band filter. The shunt capacitance was used to modify the anti-resonant frequency of the resonator for reducing the bandwidth of the filter with sacrificing low insertion loss. A narrow-band temperature compensated SAW (TCSAW) filter with low insertion loss based on a SiO2/Cu/127°YX-LiNbO3 structure was developed successfully via resonator design and evolutionary algorithm optimization. The experimental results indicate that the center frequency of the filter, relative bandwidth, and passband insertion loss are 1 514 MHz, 0.46%, and only 1.45 dB,respectively. Further, the attenuation at the frequency 20 MHz outside the passband decreases to 24 dB, remote out-of-band attenuation is greater than 30 dB, attenuation at the WiFi band is up to 48 dB, TCF is -20×10-6/℃, and the size of the device is 1.1 mm×0.9 mm.
