DPX162500DT-8028A1

RF Multiplexers Overview

The DPX162500DT-8028A1 is an LTCC diplexer manufactured by TDK Corporation, designed for RF signal conditioning in wireless applications. It operates with a low band frequency range of 1.572 GHz to 1.578 GHz and a high band range of 2.4 GHz to 2.5 GHz. The component features a 50 Ohm impedance and utilizes surface mount technology in a 0603 (1608 metric) package measuring 1.6x0.8mm. Electrical specifications include minimum attenuation of 13.00 dB for the low band and 22.00 dB for the high band, with return loss values of 14.0 dB for both bands. It supports an operating temperature range from -40°C to +85°C and holds RoHS3 compliance.

RF Multiplexers Feature Summary

RF Multiplexers Procurement Notes

Verify current production status as the component is marked Not Recommended for New Designs. Confirm availability through authorized distributors and check for recent Product Change Notifications regarding manufacturing site updates or material changes. Ensure compatibility with existing design constraints before procurement.

RF Multiplexers Selection Notes

Evaluate the specific frequency bandwidth requirements against the 1.572-1.578 GHz and 2.4-2.5 GHz ranges. Consider the 0603 footprint constraints and thermal performance within the -40°C to +85°C operational window. Assess if the LTCC construction aligns with the system's environmental durability needs.

RF Multiplexers Part Context

This part belongs to the TDK DPX series of RF diplexers, utilizing Thin Film and LTCC technologies for wireless front-end solutions. It serves as a passive signal conditioning component, distinct from active amplifiers or switches, focusing on frequency separation for multi-standard radio interfaces.

RF Multiplexers Replacement Considerations

Consult official TDK documentation for direct substitutes. Similar parts in the DPX series may offer alternative packaging or slight frequency variations but require verification of electrical parameter equivalence.
