The RO2073A-6 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 315.0 MHz. This SAW is designed for AM transmitters in automotive-keyless-entry applications operating in the USA under FCC Part 15, in Canada under DoC RSS-210, and in Italy.
