Electrical Characteristics

www.RFM.com

• Ideal for 315 MHz Automotive-Keyless-Entry Transmitters

• Very Low Series Resistance

• Quartz Stability

• Complies with Directive 2002/95/EC (RoHS)

The RO3073E 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 local oscillators operating at

approximately 315 MHz. This SAW 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.
