High frequency SAW correlator module

Surface Acoustic Wave (SAW) correlators were developed which function with central kequencies ranging fiom 300 h4Hz to 2.7 GHz. These devices enable direct translation of data to RF and back without the use of intermediate frequency stages. Several impediments to the manufacture of SAW correlators were overcome. In addition, a programmable SAW correlator built as a flip-chip combination of lithium niobate on silicon was demonstrated.
