DPX1608LL80R2455A

RF Multiplexers Overview

The DPX1608LL80R2455A is an RF diplexer manufactured by Pulse Electronics, designed for surface mount installation in a 0603 (1608 metric) package with six PCB pads. It operates across two frequency bands: a low band of 2.4GHz to 2.5GHz and a high band of 4.9GHz to 5.95GHz. The component provides a minimum attenuation of 20.00dB in the low band and 30.00dB in the high band. Both bands exhibit a return loss of 10.0dB. This device supports standard tape and reel packaging formats.

RF Multiplexers Feature Summary

• Dual-band operation supporting 2.4GHz ISM and 5GHz Wi-Fi frequencies
• High isolation via specified attenuation levels for each band
• Compact 0603 surface mount footprint for space-constrained designs

RF Multiplexers Applications

• Wireless LAN modules requiring dual-band filtering
• ISM band communication devices
• Wi-Fi enabled consumer electronics

RF Multiplexers Procurement Notes

Verify the specific datasheet version for the DPX1608LL80R2455A to confirm current electrical tolerances and mechanical dimensions. Ensure compatibility with the target PCB layout regarding the six-pad configuration. Confirm that the required attenuation and return loss specifications meet the system's interference rejection requirements before finalizing the design integration.

RF Multiplexers Selection Notes

Select this component when a compact solution is needed to separate or combine signals between the 2.4GHz and 5GHz spectrums. The choice depends on the requirement for a 0603 package size and the specific attenuation profile of 20dB and 30dB for the respective bands. Consider the manufacturing lead time and availability of tape and reel packaging for automated assembly processes.

RF Multiplexers Part Context

This part belongs to the 1608 series of RF multiplexers from Pulse Electronics. It is categorized under signal conditioning components within the radio frequency and wireless segment. The device utilizes LTCC technology typical for this manufacturer's chip filters and antennas, ensuring reliability in harsh environments while maintaining a small physical profile suitable for modern portable devices.

RF Multiplexers Replacement Considerations

The DPX1608LL66R2455A is a related variant within the same series but features different frequency ranges (up to 6GHz) and attenuation characteristics. Verify if the higher upper-frequency limit of the alternative is necessary or if the original 5.95GHz specification is sufficient for the application.
