Abstract
A wafer of lithium niobate metallized on both major surfaces is bonded to a magnesium aluminate spinel bulk acoustic delay line. The lithium niobate layer is divided into two separate electrically and mechanically isolated transducers using ion beam milling. The bulk acoustic delay line has a surface arranged to reflect a propagating acoustic wave generated by one of the divided transducers to the other of the transducers, the one transducer serving as an input and the other as an output. The acoustic delay line is suitable for broad band operation at microwave frequencies with at least 50 db isolation between the two ports.
