Rugged, Hermetic, Low-Profile TO39 Case

•

Complies with Directive 2002/95/EC (RoHS)

The RP1308 is a two-port, 180° surface-acoustic-wave (SAW) resonator in a low-profile TO39

case. It provides reliable, fundamental-mode, quartz frequency stabilization of AM, FSK, or PSK

transmitters operating at 433.92 MHz. The RP1308 was designed specifically for remote-control

and wireless security transmitters operating in Europe under ETSI I-ETS 300 220 and in Germany

under FTZ 17 TR 2100.
