IPC: H03H9/44
Filed: 1996-06-20
Abstract: PROBLEM TO BE SOLVED: To obtain a simple and inexpensive FSK(frequency shift keying) modulation transmitter by using a surface acoustic wave element equipped with a 1st input electrode which is excited at a frequency f0 , a 2nd input electrode which is excited at a frequency f1 , and a 3rd output electrode with a small number of couples of electrode fingers between those electrodes. SOLUTION: The 1st input-side inter-digital electrode 31 is provided at one end of a piezoelectric substrate 30, and a burst pulse signal of carrier frequency f0 is applied to its input terminal 34 to excite a surface acoustic wave on the piezoelectric substrate. On the other end of the piezoelectric substrate 30, the 2nd input-side inter- digital electrode 32 is provided and a burst pulse signal of carrier frequency f1 is applied to its input terminal 35 to excite a surface acoustic wave on the piezoelectric substrate. The 3rd output-side inter-digital electrode 33 is provided between the electrodes 31 and 32. The electrode 33 is made less in the number of couples of electrode fingers than the electrodes 31 and 32 to have broadband frequency characteristics, and outputs the frequencies f0 and f1 . Consequently, the simple FSK transmitter can be constituted and a spread of spectra due to a sudden shift in phase can be suppressed. A simple receiver can be constituted by replacing the input-side electrode and output- side electrode of the SAW element with each other.
