High frequency stability oscillator for surface acoustic wave-based gas sensor

This paper presents a 158 MHz surface acoustic wave (SAW) oscillator used for a gas sensor. As the oscillator element, a SAW delay line on ST-X quartz substrate with low insertion loss ( < 8 dB) and single mode selection capability was developed. Low insertion loss was achieved by an electrode wi...
