Programmable Acoustic Surface Wave Tapped Delay Lines/Matched Filters.
Abstract
The design, fabrication and performance of three programmable 32/64/128 acoustic surface wave tapped delay line matched filters are described. The devices were temperature stable ST cut quartz tapped delay lines in combination with silicon on sapphire integrated control circuit and external switches to allow correlation of spread spectrum biphase coded waveforms of 32, 64, and 128 chips at a 70 MHz IF frequency with 10 MHz chip rate.
