DPX1608LKEFR2455L

RF Multiplexers Overview

The DPX1608LKEFR2455L is a surface-mount diplexer manufactured by Pulse Electronics, designed for signal conditioning in wireless applications. It operates within the 2.4 GHz and 5 GHz frequency bands, specifically covering passbands of 2400-2500 MHz and 5150-5875 MHz. The component utilizes a 0603 (1608 metric) package with six pads, ensuring compatibility with standard SMD/SMT board mounting processes. It maintains a nominal impedance of 50 Ohms and functions reliably across an operating temperature range from -40°C to +85°C. This device supports Wi-Fi 6/6E and Bluetooth connectivity requirements.

RF Multiplexers Procurement Notes

Verify the specific suffix 'EF' against official datasheets to confirm the exact high-band passband definition (5150-5875 MHz). Ensure the 0603 package dimensions align with PCB land pattern specifications. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement orders.

RF Multiplexers Selection Notes

Select this component when designing systems requiring simultaneous operation in 2.4 GHz and 5 GHz ISM bands. The 0603 size offers a balance between performance and miniaturization. Consider thermal management capabilities given the -40°C to +85°C operational range. Validate impedance matching at 50 Ohms within the target circuit topology.

RF Multiplexers Part Context

This part belongs to the DPX series of diplexers from Pulse Electronics, which are widely used in modern wireless communication devices. The series leverages Low-Temperature Co-fired Ceramic (LTCC) technology to achieve high Q-factors and precise filtering characteristics. These components are essential for managing spectral interference in dense RF environments.

RF Multiplexers Replacement Considerations

Direct substitutes must match the 0603 package, 50 Ohm impedance, and identical passband frequencies (2400-2500 MHz and 5150-5875 MHz). Verify that alternative parts offer comparable insertion loss and rejection specs. Cross-reference pinout configurations to ensure compatibility without PCB redesign.
