The RO2136A is a true one-port, surface-acoustic-wave (SAW) resonator in a low profile surface-mount

ceramic case. It provides reliable, fundamental-mode, quartz frequency stabilization of local oscillators oper-

ating at approximately 432.920 MHz. This SAW is designed specifically for remote-control and wireless

security receivers operating in Europe under ETSI I-ETS 300 220 and in Germany under FTZ 17 TR 2100.

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

includes parasitic capacitance with “NC” pads unconnected. Case parasitic

capacitance is approximately 0.05pF. Transducer parallel capacitance can be
