5-GHz Antisymmetric Mode Acoustic Delay Lines in Lithium Niobate Thin Film
Ruochen Lu, Yansong Yang, Ming-Huang Li +2
We present the first group of acoustic delay lines (ADLs) at 5 GHz, using the first-order antisymmetric (A1) mode in Z-cut lithium niobate thin films. The demonstrated ADLs signifi…
4.5 GHz Lithium Niobate MEMS Filters with 10% Fractional Bandwidth for 5G Front-ends
Yansong Yang, Ruochen Lu, Liuqing Gao +1
This paper presents a new class of micro-electro-mechanical system (MEMS) C-band filters for 5G front-ends. The filter is comprised of resonators based on the first-order asymmetri…
A 300-500 MHz Tunable Oscillator Exploiting Ten Overtones in Single Lithium Niobate Resonator
Ali Kourani, Ruochen Lu, Anming Gao +1
This paper presents the first voltage-controlled MEMS oscillator (VCMO) based on a Lithium Niobate (LiNbO3) lateral overtone bulk acoustic resonator (LOBAR). The VCMO consists of a…
A Radio Frequency Non-reciprocal Network Based on Switched Acoustic Delay Lines
Ruochen Lu, Tomas Manzaneque, Yansong Yang +3
This work demonstrates the first non-reciprocal network based on switched low-loss acoustic delay lines. The 4-port circulator is built upon a recently reported frequency-independe…
