The RO2043 is a true one-port, 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 303.825 MHz. The RO2043-1 is designed specitically for low-power AM transmitters on remote-control and wireless alarm applications operating in the USA under FCC Part15, in Japan, in Australia, in Korea, and elsewhere.
