• Ideal for 916.5 MHz FCC Part 15 Transmitters
• Very Low Series Resistance
• Quartz Stability
• Complies with Directive 2002/95/EC (RoHS)
The RO3144E is a true one-port, surface-acoustic-wave (SAW) resonator in a surface-mount ceramic case.
It provides reliable, fundamental-mode stabilization of fixed-frequency transmitters operating at 916.5 MHz.
This SAW is designed specifically for remote-control and data-link transmitters operating in the USA under
FCC Part 15 regulations.
