Description

Ideal for 315.0 MHz Transmitters Low Series Resistance Quartz Stability Rugged, Hermetic, Low-Profile TO39 Case Complies with Directive 2002/95/EC (RoHS)

The RO2073 is a true one-port, surface-acoustic-wave (SAW) resonator in a low-profile TO39 case. It pro-vides reliable, fundamental-mode, quartz frequency stabilization of fixed-frequency transmitters operating at 315 MHz. The RO2073 is designed specifically for wireless remote controls and security transmitters, typi-cally for automotive-keyless-entry, operating in the USA under FCC Part 15, in Canada under DoC RSS-210,and in Italy.
