• Ideal for 433.92 MHz Superheterodyne Receiver LOs

• Very Low Series Resistance

• Quartz Stability

• Surface-mount Ceramic Case

• Complies with Directive 2002/95/EC (RoHS)

The RO3102A-1 is a true one-port, surface-acoustic-wave (SAW) resonator in a surface-mount, ceramic case.

It provides reliable, fundamental-mode, quartz frequency stabilization of local oscillators operating at

approximately 423.22 MHz. This SAW is designed for 433.92 MHz superhet receivers using a 10.7 MHz IF.

Applications include remote-control and wireless security receivers operating in Europe under ETSI

I-ETS 300 220.

This equivalent RLC model approximates resonator performance near

the resonant frequency and is provided for reference only. The

two terminals measured at low frequency (10 MHz) with a capacitance

meter. The measurement includes parasitic capacitance with "NC”

pads unconnected. Case parasitic capacitance is approximately

0.05 pF. Transducer parallel capacitance can by calculated as:
