Electrical Characteristics

www.RFM.com E-mail: info@rfm.com

• 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

provides 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,

typically for automotive keyless entry, operating in the USA under FCC Part 15, in Canada under DoC

RSS-210, and in Italy.
