Abstract :
A surface acoustic wave (SAW) correlator that satisfies FCC bandwidth requirements for ultra-wideband (UWB) operation has been built and tested. The correlator operates within the 3.1 to 10.6 GHz bandwidth region and uses bi-phase shift keying (BPSK) modulation to achieve a spreading of the main lobe to a 25% bandwidth. This device is capable of spreading or de-spreading a UWB signal directly to or from base-band to microwave frequencies
