A BRAND OF AKOUSTIS

RF1432C• 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)• Tape and Reel Standard per ANSI/EIA-481• Moisture Sensitivity Level: 1319.500 MHz
SAW Filter

The RF1432C is a low-loss, compact and economical surface-acoustic-wave (SAW) filter designed toprovide front-end selectivity in 319.500 MHz receivers. Receiver designs using this filter include superhet
with 10.7 MHz or 500 kHz IF, direct conversion and superregen.
This coupled-resonator filter (CRF) uses selective null placement to provide suppression, typically greaterthan 40 dB, of the LO and image spurious responses of superhet receivers with 10.7 MHz IF. RFMi'sadvanced 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.
