FAQ
Q1: What are the standard frequency points for Suzhou Hangjing's SMD SAW Resonator 2.0 x 1.6-SR21S4 Series?
A: Standard frequency points are 303, 315, 390, 433.92, 435, 72, while we can customize according to clients' specific parameter.
Q2: Common Problems and Solutions for Surface Acoustic Wave (SAW) Resonators?
A: Frequency Deviation
1)Symptom: The output frequency of the circuit does not match the nominal frequency of the SAW resonator, and the deviation exceeds the allowable range.
2)Cause: Load Capacitance Mismatch: SAW resonators are highly sensitive to load capacitance (CL). A mismatch between the actual load capacitance in the circuit and the value required by the resonator's design is the most common cause of frequency shift.
3)Solutions: Precise Load Capacitance Matching: Use accurate matching capacitors (typically two external capacitors) in the oscillator circuit as specified in the datasheet. Fine-tuning these capacitors can "pull" the frequency.
