DPX1608LKEMR2455L

RF Multiplexers Overview

The DPX1608LKEMR2455L is a surface-mount RF diplexer manufactured by Pulse Electronics, designed for signal conditioning in wireless applications. 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 utilizes a 0603 (1608 metric) package with six printed circuit board pads. It is RoHS compliant and features a standard factory packaging quantity of 4,000 units per reel.

RF Multiplexers Feature Summary

• Supports dual-band operation for 2.4GHz and 5GHz wireless protocols
• Compact 0603 surface-mount footprint for space-constrained designs
• LTCC technology construction for stable thermal performance

RF Multiplexers Applications

• Wi-Fi routers and access points
• Bluetooth modules
• IoT sensor nodes
• Wireless communication devices

RF Multiplexers Procurement Notes

Verify the specific suffix 'MR' against the official datasheet to confirm the exact attenuation and return loss specifications, as these parameters vary significantly within the DPX1608 series. Ensure the ordering quantity aligns with the manufacturer's standard reel size of 4,000 units. Confirm that the 0603 package dimensions match the target PCB layout requirements before finalizing procurement.

RF Multiplexers Selection Notes

Select this component when a compact solution is required for separating 2.4GHz and 5GHz signals in single-antenna systems. The 0603 package offers a smaller profile compared to larger diplexers. Verify that the insertion loss and isolation levels meet the system's noise floor requirements. Consider the operating temperature range of -40°C to +85°C for environmental compatibility.

RF Multiplexers Part Context

This part belongs to the DPX1608 series of LTCC diplexers from Pulse Electronics. These components are engineered for high-volume consumer electronics manufacturing. The series provides various configurations to support different Wi-Fi and Bluetooth standards. The 1608 metric designation indicates the standardized case size used across multiple variants in the product line.

RF Multiplexers Replacement Considerations

Direct substitutes include DPX1608LL66R2455A and DPX1608LL65R2455A. Verify pinout compatibility and electrical parameter alignment, specifically attenuation and return loss values, before substitution. Other variants such as DPX1608LKECR2455L may share the package but differ in frequency response.
