Abstract

This paper studies a feasibility of ultra-wideband SAW device for the matched filter device useful for the sensing device and local area CDMA communication systems with the pulse position spread spectrum signal modulation scheme at GHz frequency range. We propose an excellent coded device suited for realizing using SAW device. We clarify difference of the effect of so-called second order effect on these devices from that of narrow bandwidth devices and discuss device design methods. We discuss basic circuits of programmable device coupled with CMOS devices.
