RF3210D

RF3210D Ideal Front-End Filter for Domestic Wireless Receivers Low-Loss, Coupled-Resonator Quartz Design Simple External Impedance Matching Complies with Directive 2002/95/EC (RoHS) Pb 303.825 MHz SAW Filter The RF3210D is a low-loss, compact, and economical surface-acoustic-wave (SAW) filter designed to provide front-end selectivity in 303.825 MHz receivers. Receiver designs using this filter include superheterodyne with 10.7 MHz or lower IF frequencies, direct conversion receivers and superregenerative receivers. 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.
