Notes:

• Ideal Front-End Filter for European Wireless Receivers

• Low-Loss, Coupled-Resonator Quartz Design

• Simple External Impedance Matching

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

The RF1396C is a low-loss, compact, and economical surface-acoustic-wave (SAW) filter

designed to provide front-end selectivity in 434.420 MHz receivers. Receiver designs using this

filter include superhet with 10.7 MHz or 500 kHz IF, direct conversion and superregen. Typical

applications of these receivers are wireless remote-control and security devices operating in

Europe under ETSI I-ETS 300 220.

This coupled-resonator filter (CRF) uses selective null placement to provide suppression, typically

greater than 40 dB, of the LO and image spurious responses of superhet receivers with 10.7 MHz

IF. RFM’s advanced SAW design and fabrication technology is utilized to achieve high

performance and very low loss with simple external impedance matching.

Frequency aging is the change in fc with time and is specified at +65°C or less. Aging may exceed the specification for prolonged temperatures

above +65°C. Typically, aging is greatest the first year after manufacture, decreasing significantly in subsequent years.
