RF3606D

Overview

The RF3606D is a surface-mount SAW bandpass filter manufactured by RFMi, designed for signal conditioning applications. It operates within a frequency range of 383.1 MHz to 396.9 MHz with a center frequency of 390 MHz and a bandwidth of 16 MHz. The component features an insertion loss of 1.4 dB and supports impedances of 50 Ohms and 150 Ohms. Rated for a maximum voltage of 5 V, it functions reliably between -40°C and +85°C. Packaged in an SM-3838-8 SMD/SMT form factor, it weighs approximately 63 mg.

Feature Summary

• Provides selective signal filtering within the specified 383.1 MHz to 396.9 MHz bandpass range
• Supports dual impedance configurations of 50 Ohms and 150 Ohms for flexible circuit integration
• Utilizes Surface Acoustic Wave (SAW) technology for efficient signal conditioning

Applications

• TRC105 Transceiver systems
• RF signal conditioning circuits
• Bandpass filtering in communication modules

Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with RFMi or authorized distributors before procurement. Confirm that the SM-3838-8 package dimensions align with your PCB footprint requirements. Ensure the operating temperature range of -40°C to +85°C meets your environmental specifications. Cross-reference the 5 V rating and impedance values against your circuit design parameters to ensure compatibility.

Selection Notes

Select the RF3606D when a 390 MHz center frequency with a 16 MHz bandwidth is required for TRC105 transceiver applications. Its dual impedance capability allows adaptation to both 50 Ohm and 150 Ohm system interfaces. The low insertion loss of 1.4 dB makes it suitable for maintaining signal integrity in sensitive RF paths. Consider the SMD packaging for automated assembly processes.

Part Context

This component belongs to the RF series of bandpass filters from RFMi, which offers a wide range of SAW solutions for frequencies from approximately 30 MHz to 3.7 GHz. The RF3606D specifically targets the 390 MHz region, providing a specialized solution for narrowband filtering needs in industrial and communication equipment where precise frequency selection is critical.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate other RFMi models within the same frequency range only if they match the exact impedance and package constraints.
