RO3156A_15 Datasheet, PDF (1/3 Pages) Murata Manufacturing Co., Ltd. – 868.95 MHz SAW Reso

• Designed for European 868.95 MHz SRD Transmitters
• Very Low Series Resistance
• Quartz Stability
• Surface-mount Ceramic Case
• Complies with Directive 2002/95/EC (RoHS) _Pb
The RO3156A is a one-port surface-acoustic-wave (SAW) resonator packaged in a surface-mount ceramic
case. It provides reliable, fundamental-mode quartz frequency stabilization of fixed-frequency transmitters
operating at 868.95 MHz. The RO3156A is designed specifically for SRD transmitters operating in Europe
under ETSI EN 300 220-2.
