Resonator  
The RO3112 is a true one-port, surface-acoustic-wave (SAW) resonator in a low-profile TO39 case. It provides  
reliable, fundamental-mode, quartz frequency stabilization of local oscillators operating at approximately  
433.42 MHz. The RO2112 is designed for IC based 433.92 MHz superhet receivers with 500 kHz IF (Philips  
UAA3201T). Applications include remote-control and wireless security devices operating in Europe under  
ETSI I-ETS 300 220 and in Germany under FTZ 17 TR 2100.
