Abstract
A unit comprising a printed board on which a plurality of surface acoustic wave (SAW) devices are installed. Each SAW device comprises a piezoelectric substate on which arrays of strip electrodes are formed. A cover is mounted over the SAW devices to hermetically seal the surfaces of the SAW devices on which the electrodes are formed. The terminals of the board are directly coupled to the terminals of the SAW devices.
