Designed for 315 MHz Transmitters Nominal Insertion Phase Shift of 180° at Resonance Quartz Stability Rugged, Hermetic, Low-Profile TO39 Case
The RP1239 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 low-power AM and FSK transmitters operating at 315.0 MHz for use in the United Kingdom under DTI MPT 1340 and in the USA under FCC Part 15. Applications include remote-control and wireless security devices. This is a pin-for-pin replacement in preexisting transmitter circuits utilizing two-port, 180° SAW resonators.
