The RO2102a-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 fixed-frequency oscillators operating

at 423.22 MHz. The RO2102A-1 is designed specifically for the LO of 433.92 MHz superhet receivers in re-

mote-control and wireless security applications operating under ETSI I-ETS 300 220 in Europe.

the static (nonmotional) capacitance between the two terminals measured at

low frequency (10 MHz) with a capacitance meter. The measurement

includes parasitic capacitance with a floating case. For usual grounded case
