Overview
The RF3709E is a general-purpose radio frequency surface acoustic wave (SAW) filter manufactured by RFMi, an Akoustis brand. Designed for operation at a center frequency of 433.92 MHz, this component supports the ISM band range from 433.27 MHz to 434.57 MHz. It features a bandwidth of 1.07 MHz and an insertion loss of 2.2 dB. The device is housed in a compact 6-SMD, no-lead package, suitable for surface-mount assembly.
Feature Summary
- Utilizes surface acoustic wave technology for signal conditioning
- Optimized for 433.92 MHz general purpose RF applications
- Compact 6-SMD no-lead surface mount package
Applications
- General purpose RF filtering
- ISM band equipment
- Wireless communication modules
Procurement Notes
Verify the manufacturer designation as RFMi or Akoustis-RFMI on the component marking and datasheet header. Confirm the specific suffix indicates the tape and reel packaging variant if required for automated assembly. Ensure the center frequency specification matches the 433.92 MHz requirement for the target application circuit.
Selection Notes
Select this component when a SAW filter with a 1.07 MHz bandwidth is required for the 433 MHz band. Consider the 2.2 dB insertion loss impact on system sensitivity. The 6-SMD package dictates the PCB footprint design. Verify compatibility with the operating temperature range specified in the official datasheet before integration.
Part Context
RFMi, now part of Akoustis, specializes in RF components using SAW, crystal, and ceramic technologies. This filter belongs to their lineup of signal conditioning devices designed for digital and wireless communications.
