Description

Ideal for 315 MHz Automotive-Keyless-Entry Transmitters Very Low Series Resistance Quartz Stability Complies with Directive 2002/95/EC (RoHS)

The RO2073D is a true one-port, surface-acoustic-wave (SAW) resonator in a surface-mount, ceramic case.

RO2073D provides reliable, fundamental-mode, quartz frequency stabilization of local oscillators operating at approximately
315 MHz. This SAW RO2073D 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.
