RF3700D

The RF3700D is a low-loss, compact, and economical surface-acoustic-wave (SAW) filter designed to provide front-end selectivity in 372.00 MHz receivers. Receiver designs using this filter include superheterodyne with 10.7 MHz or 500 kHz IFs, direct conversion receivers and superregenerative receives. Typical applications for these receivers are wireless remote control and security.

This coupled-resonator filter (CRF) uses selective null placement to provide suppression, typically greater than 40 dB, of the LO and image spurious responses in superheterodyne receivers with 10.7 MHz IFs. Murata's advanced SAW design and fabrication technology is utilized to achieve high performance and very low loss with simple external impedance matching.
