RO2101D Datasheet, PDF (1/2 Pages) RF Monolithics, Inc – 433.92 MHz SAW Resonator

RO2101D
• Ideal for European 433.92 MHz Transmitters
• Very Low Series Resistance
• Quartz Stability
• Complies with Directive 2002/95/EC (RoHS) Pb
The RO2101D 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 transmitters operat-
ing at 433.92 MHz. This SAW is designed specifically for remote-control and wireless security transmitters op-
erating in Europe under ETSI I-ETS 300 220 and in Germany under FTZ 17 TR 2100.
