RP1237 418.0 MHz SAW Resonator Designed for 418.00 MHz Transmitters Nominal Insertion Phase Shift of 180° at Resonance Quartz Stability Rugged, Hermetic, Low-Profile TO39 Case Complies with Directive 2002/95/EC (RoHS) Pb The RP1237 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 fixed-frequency transmitters operating at 418.0 MHz. The RP1237 is designed specifically for remote-control and wireless security transmitters operating in the United Kingdom under DTI MPT 1340 and in the USA under FCC Part 15.231 regulations.
