DPX105850DT-6018A1

RF Multiplexers Overview

The DPX105850DT-6018A1 is a multilayer diplexer designed for RF signal conditioning, manufactured by TDK Corporation. It operates across two distinct frequency bands: a low band from 2.4 GHz to 2.5 GHz and a high band from 5.15 GHz to 5.85 GHz. The component utilizes LTCC technology and is housed in a compact 0402 (1005 metric) surface-mount package with four terminals. Key electrical specifications include a maximum insertion loss of 0.5 dB. Attenuation performance is specified with a minimum of 17.00 dB for the low band and 25.00 dB for the high band, with maximum attenuation values of 33.00 dB and 32.00 dB respectively. Return loss is rated at 10.0 dB for both bands.

RF Multiplexers Feature Summary

• Integrates dual-band filtering capabilities within a single compact surface-mount footprint using LTCC construction.

RF Multiplexers Applications

• Wireless LAN modules requiring simultaneous 2.4 GHz and 5 GHz operation
• Bluetooth and Wi-Fi coexistence interfaces
• Compact mobile device RF front-end assemblies

RF Multiplexers Procurement Notes

Verify current availability status as the component is marked not recommended for new designs. Confirm that the ordering suffix corresponds to the specific tape and reel configuration required for automated assembly processes. Ensure compliance with RoHS3 standards and check for any pending product change notices affecting long-term supply.

RF Multiplexers Selection Notes

Select this component when space constraints necessitate a 0402 form factor for dual-band separation. Evaluate thermal stability requirements, noting the design supports stable operation up to 85°C. Compare attenuation specs against system interference thresholds to ensure adequate isolation between the 2.4 GHz and 5 GHz channels.

RF Multiplexers Part Context

This part belongs to the TDK DPX series of RF multiplexers. These components are engineered for high-reliability applications in wireless communications.
