Wide Band Monolithic Crystal Filters Using Lithium Tantalate

Received01 Dec 1975


The construction and performance of wide bandwidth monolithic crystal filters is demonstrated using single crystal lithium tantalate. Important steps in the fabrication of the filter and the necessary design criteria are discussed. The Bechmann conditions for single mode energy trapping and the inter-resonator coupling relationships are given. Using the data reported, filters operating at third harmonic frequencies (approximately 50 MHz) have been constructed with bandwidths up to 0.75%.
