DPX1608LJFKR2455L

RF Multiplexers Overview

The DPX1608LJFKR2455L is a surface-mount diplexer manufactured by Pulse Electronics, designed for signal conditioning applications. It operates within the 2.4 GHz and 5 GHz frequency bands, specifically covering bandwidths from 2400 MHz to 2500 MHz and 4900 MHz to 5950 MHz. The component utilizes a 0603 (1608 metric) package with six PCB pads and supports SMD/SMT termination types. It functions reliably across an operating temperature range of -40°C to +85°C and maintains a standard impedance of 50 Ohms.

RF Multiplexers Procurement Notes

Verify the specific suffix 'KR' against official Pulse Electronics documentation to confirm exact electrical tolerances and passband characteristics. Ensure compatibility with existing board layouts regarding the 0603 footprint and six-pad configuration. Confirm RoHS compliance status through current manufacturer declarations prior to final procurement decisions.

RF Multiplexers Selection Notes

Select this component when space-constrained designs require dual-band filtering within a 0603 envelope. Evaluate insertion loss and return loss specifications against system requirements for the 2.4 GHz and 5 GHz bands. Consider thermal stability and MSL ratings for manufacturing processes involving reflow soldering at elevated temperatures.

RF Multiplexers Part Context

This part belongs to the DPX series of diplexers from Pulse Electronics, focusing on signal conditioning for wireless infrastructure. The series typically employs Low-Temperature Co-fired Ceramic (LTCC) technology to achieve high performance in miniature packages. These components are integral to modern multi-standard radio architectures requiring efficient spectrum management.

RF Multiplexers Replacement Considerations

DPX1608LL65R2455A offers similar 2.4/5 GHz coverage but may differ in attenuation specs. DPX1608LKEFR2460L covers wider 5-7 GHz bands suitable for Wi-Fi 7. Verify pinout and impedance matching before substituting.
