SAW
The RO3103E is a true one-port, surface-acoustic-wave (SAW) resonator in a surface-mount, ceramic case.
It provides reliable, fundamental-mode, quartz frequency stabilization of fixed-frequency transmitters
operating at 418.00 MHz. This SAW is designed specifically for AM transmitters in wireless security and
remote control applications operating in the USA under FCC Part 15, in Australia, in Japan, and in Korea.

8. Turnover temperature, TO, is the temperature of maximum (or turnover)
2. The center frequency, fC, is measured at the minimum insertion loss point,
frequency, fO. The nominal frequency at any case temperature, TC, may be
ILMIN, with the resonator in the 50 Ω test system (VSWR ≤ 1.2:1). The
shunt inductance, LTEST, is tuned for parallel resonance with CO at fC.
Typically, fOSCILLATOR or fTRANSMITTER is approximately equal to the
calculated from: f = fO [1 - FTC (TO -TC)2]. Typically oscillator TO is
approximately equal to the specified resonator TO.
