“…Acoustic wave (AW) filter modules are key components [ 2 ], but their performance degrades as frequency increases [ 3 ]. Compact RF passive components are realized by using low-temperature co-fired ceramic (LTCC) technologies, including diplexers [ 4 , 5 , 6 , 7 , 8 , 9 , 10 ], duplexers [ 11 , 12 , 13 ], band stop filters [ 14 , 15 ], and low pass filters [ 16 ]. However, when overall space constraints are considered, this may not be a suitable solution for a mobile phone.…”

This study designs antenna-plexers, including a surface acoustic wave (SAW) extractor and an upper- and mid-high band (UHB + MHB) diplexer, for LTE 4G and 5G bands using carrier aggregation. The SAW extractor combines a bandpass filter (BPF) and a band-stop filter (BSF) in a single unit that consists of eight modified Butterworth–van Dyke (mBVD) resonators that resonate in parallel with an inductor and SAW resonators. This BSF behaves as a high-pass filter at frequencies lower than the designed WIFI band and as a capacitor at higher frequencies. The SAW extractor meets product specifications in the frequency range 0.7 to 2.7 GHz. The UHB + MHB diplexer, which is composed of a microwave filter, a SAW filter, and a simple matching inductor, uses frequency response methods to create an RF component for 2.4 GHz + WIFI 6E applications. The design uses a SAW’s interdigital transducer (IDT) structure, and the experimental results are in agreement with the simulation results, so the design is feasible.
