RO3112A

• Designed for 433.92 MHz Superheterodyne Receiver LOs

• Very Low Series Resistance

• Quartz Stability

• Surface-mount Ceramic Case

• Complies with Directive 2002/95/EC (RoHS)

The RO3112A 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 local oscillators operating at

433.42 MHz. The RO3112Ais designed for 433.92 MHz superheterodyne receivers with a 500 kHz IF (Philips

UAA3201T). Applications include remote-control and wireless security receivers operating in Europe under

ETSI EN 300 220-2.
