SAW RESONATOR has generally 2 types of 1-port type and 2-port type.
1-port SAW RESONATOR is basically a 2 terminal device and its application is similar to that of quartz bulk wave resonator or ceramic resonator. Most of the application circuit is Colpitts or similar type that can be made with low cost. 1-port SAW RESONATOR is also applicable to the VCO (Voltage Controlled Oscillator) application.
2-port SAW RESONATOR is a kind of very narrow, low loss band-pass filter. Oscillation circuit is mostly like an RF amplifier with a feedback loop. SARCC series is 1-port SAW RESONATOR. Later application data is oscillation circuit by 1-port SAW RESONATOR.
