Introduction
The RF1439E is a low-loss, compact, and economical surface-acoustic-wave (SAW) filter designed to provide front-end selectivity in 315.0 MHz receivers. Receivers using this filter include superheterodynes with IF’s at 10.7 MHz or 500 kHz, plus direct conversion and superregeneratives. This coupled-resonator filter (CRF) uses selective null placement to provide typically more than 40 dB suppression of LO and image responses in superheterodyne receivers with 10.7 MHz IF’s. Advanced SAW design and fabrication technology is utilized to achieve high performance and very low loss with simple external impedance matching.
Features
- Ideal Front-End Filter for Wireless Receivers
- Low-Loss, Coupled-Resonator Quartz Design
- Simple Impedance Matching
- Complies with Directive 2002/95/EC (RoHS)
- Moisture Sensitivity Level: 1
Applications
- Wireless remote-control and security devices operating in North America
