Abstract
Surface acoustic wave devices (160) as well as other electronic devices, can be mounted into the sides of ceramic blocks (150) that comprise a ceramic block filter device. The surface acoustic wave device as mounted in the filter block does not require or displace volume that would be required to mount the surface acoustic wave devices in their own housings.
