A surface transverse wave-based MSK system

摘要

A minimum-shift-keyed (MSK) system using one 1-GHz surface-transverse-wave (STW) resonator in the transmitter and two identical STW resonators in the receiver is described. It is shown to operate with data rates of over 100 kb/s and consume 150 mW. The system has a very high sensitivity and is tolerant to additive noise. Since the signal is never up- or down-converted. this system eliminates high power consumption. The system should find applications in cellular radios and in industrial communications.
