Description

The RO2073E is a true one-port, surface-acoustic-wave (SAW) resonator in a surface-mount, ceramic case.RO2073E provides reliable, fundamental-mode, quartz frequency stabilization of local oscillators operating at approx-imately 315 MHz. This SAW RO2073E was 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.
