Conventional synthesis methods used in the design of acoustic-wave (AW) microwave filters
suffer from limited achievable fractional bandwidth (FBW) and weak out-of-band (OOB) …

In this article, a general synthesis method for acoustic wave filters and duplexers with
predetermined spectrum mask and technical requirements is developed and demonstrated …

This work proposes a 2-D electrode structure consisting of rotated interdigital transducers
(IDTs) and matched waveguide boundaries. By tilting the waveguide boundary so that the …

The bandwidth enhancement of the acoustic‐wave‐lumped‐element resonator (AWLR)‐
based filter has been investigated for a long time. However, few researches are focused on …

This study proposes a single-stage lattice-type acoustic filter using an analytical solution
method for either a narrow passband filter or a wider passband filter using two kinds of …

This paper presents three design methods for acoustic wave (AW) filters: the direct
conversion design method, the slope parameter method, and the band edge fitting method …

In this article, a novel compact Band-5 RX surface acoustic wave (SAW) bandpass filter with
high selectivity is proposed. The filter is composed of two identical double-mode SAW …

Polynomial function based synthesis methodologies have been extensively studied in the
design of acoustic-wave (AW) filters to achieve the filter performance requirements of the …
