Description
RF1301
Ideal Front-End Filter for European Wireless Receivers Low-Loss, Coupled-Resonator Quartz Design Simple External Impedance Matching Rugged TO39 Hermetic Package Pb Complies with Directive 2002/95/EC (RoHS)
499.250 MHz SAW Filter
The RF1301 is a low-loss, compact and economical surface-acoustic-wave (SAW) filter designed to provide front-end selectivity in 499.250 MHz receivers. Typical applications of these FSK receivers are wireless remote-control and security devices operating in Europe. RFM’s advanced SAW design and fabrication technology is utilized to achieve high performance and very low loss with simple external impedance matching (not included). Quartz construction provides excellent frequency stability over a wide temperature range.
