DPX204752DT-4028A1

RF Multiplexers Overview

The DPX204752DT-4028A1 is an RF diplexer manufactured by TDK Corporation, designed for surface mount installation in a 0805 (2012 metric) package with six PCB pads. It operates within two distinct frequency bands: a low band ranging from 2.3GHz to 2.5GHz and a high band spanning 3.17GHz to 4.76GHz. The component utilizes Low-Temperature Co-Fired Ceramic (LTCC) technology to achieve low insertion loss and latency. Key electrical specifications include a minimum attenuation of 20.00dB for both frequency bands and return loss values of 7.0dB for the low band and 10.0dB for the high band.

RF Multiplexers Feature Summary

• Utilizes LTCC technology for optimized signal integrity
• Provides dual-band separation for RF signal routing
• Ensures consistent attenuation across specified frequency ranges

RF Multiplexers Applications

• Wireless communication modules requiring dual-band filtering
• RF front-end circuits in mobile devices
• IoT hardware utilizing 2.4GHz and sub-6GHz frequencies

RF Multiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS3 compliance status prior to integration. Check datasheet revisions for any updates regarding land pattern geometry, as soldering characteristics directly influence electrical performance. Ensure storage conditions align with MSL Level 1 requirements to maintain component reliability during assembly processes.

RF Multiplexers Selection Notes

Select this component when specific dual-band isolation between 2.3-2.5GHz and 3.17-4.76GHz is required within a compact 0805 footprint. Consider the LTCC construction for applications demanding stable thermal performance and low latency. Evaluate return loss requirements against system specifications to ensure impedance matching compatibility. Verify that the package dimensions fit the target PCB layout constraints.
