This paper introduces a novel quadruplet structure in waveguide technology, comprising a TM cavity within two λ/4 TE cavities. This structure demonstrates the capability of generating responses with f...
This article describes a new waveguide filter topology based on λg/4 resonators and frequency-variant couplings (FVCs) implemented with modified E-plane stubs. The combination of the new stubs with λg...
This paper presents a novel three-way nine-pole compact cross-coupled resonator network that simultaneously realizes a filtering function and a three-way splitter or combiner function. These functiona...
This paper addresses the design and development of a novel trisection topology in evanescent-mode waveguide technology providing one below-passband transmission zero. The innovative proposal achieves ...
In this paper, 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 (DMS), which are symmetr...
This paper reports the first piezoelectric acoustic filter in periodically poled piezoelectric film (P3F) lithium niobate (LiNbO3) at 23.8 GHz with low insertion loss (IL) of 1.52 dB and 3-dB fraction...
This work presents a fin-mounted A5-mode Lamb wave acoustic resonator based on Y128°-cut lithium niobite thin film for millimeter wave (mmWave) frequencies. By using a new fin-mounted structure and op...
Emerging wireless communication standards call for higher carrier frequencies, presenting challenges to frontend filter design for 5G and beyond. Bulk acoustic wave (BAW) resonators have been widely e...
This work reports the first study of periodically poled piezoelectric film (P3F) lithium niobate (LiNbO₃) resonators at cryogenic temperatures. We experimentally investigate the temperature dependency...
This paper presents an energy-efficient transmitter and receiver system based on multi-channel integrated circuits in CMOS 45 nm technology, in-package antenna feeds and high directivity planar lenses...
