DPX205950DT-9026A1

RF Multiplexers Overview

The TDK DPX205950DT-905950DT-9026A1 is a surface-mount SAW diplexer designed for signal conditioning in RF applications. It operates with two distinct frequency bands: 2.4 GHz to 2.5 GHz and 4.9 GHz to 5.95 GHz. The component features a 50 Ohm impedance and utilizes an SMD/SMT termination type within a compact 2 mm x 1.25 mm x 0.6 mm package. It supports board mounting and functions within a temperature range of -40°C to +85°C. Key electrical specifications include an insertion loss of 0.65 dB, low-band attenuation of 10.00dB to 35.00dB, high-band attenuation of 15.00dB to 27.00dB, and return losses of 15.5dB and 17.0dB for the respective bands.

RF Multiplexers Feature Summary

• Integrates dual-band filtering capabilities for simultaneous 2.4 GHz and 5 GHz WLAN operations using SAW technology.
• Provides high isolation between frequency bands through specified attenuation levels for both low and high bands.
• Utilizes a compact 0805 (2012 metric) surface-mount footprint suitable for space-constrained PCB layouts.

RF Multiplexers Applications

• Wireless Local Area Network (WLAN) systems
• Mobile phone RF front-end modules
• Bluetooth connectivity devices

RF Multiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct frequency band alignment and packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into production assemblies. Cross-reference the ECAD model dimensions with the mechanical drawing to validate board layout compatibility.

RF Multiplexers Selection Notes

Select this component when designing circuits requiring separation of 2.4 GHz and 5 GHz ISM bands within a single RF path. The 50 Ohm impedance matches standard transmission line characteristics. Consider the operating temperature range and insertion loss specifications relative to system power budget constraints. Ensure the surface-mount package size fits the available real estate on the target printed circuit board.
