DPX165900DT-8125A1

RF Multiplexers Overview

The DPX165900DT-8125A1 is an RF diplexer manufactured by TDK Corporation, designed for surface-mount installation in a compact 0603 (1608 Metric) package with six printed circuit board pads. It operates within two distinct frequency bands: a low band ranging from 2.4 GHz to 2.5 GHz and a high band spanning 5.1 GHz to 5.9 GHz. The component provides specific attenuation characteristics, offering minimum low-band attenuation of 18.00 dB and maximum high-band attenuation of 33.00 dB. Return loss performance is rated at 22.0 dB for the low band and 13.0 dB for the high band. It functions reliably across an operating temperature range of -40°C to +85°C.

RF Multiplexers Feature Summary

• Dual-band RF signal separation capability supporting Wi-Fi and cellular applications
• Compact surface-mount design utilizing a standard 0603 footprint for space-constrained layouts
• High isolation performance through specified attenuation levels in both passbands
• Robust thermal stability suitable for demanding electronic environments

RF Multiplexers Applications

• Wireless local area network (WLAN) modules requiring dual-band filtering
• Mobile communication devices integrating multiple radio frequency transceivers
• IoT gateways and routers utilizing combined 2.4 GHz and 5 GHz connectivity
• Embedded systems requiring compact RF front-end components

RF Multiplexers Procurement Notes

Verify the complete part number including the suffix A1 to ensure correct band specifications. Confirm that the required packaging format matches availability options such as cut tape or reel quantities. Check RoHS compliance status if environmental regulations apply to the final assembly. Ensure ESD handling procedures are followed during storage and installation due to the sensitive nature of RF components.

RF Multiplexers Selection Notes

Select this component when a small form factor is critical for the PCB layout. Compare return loss requirements against system specifications to ensure adequate impedance matching. Evaluate the attenuation values to confirm sufficient isolation between the 2.4 GHz and 5.1–5.9 GHz bands. Consider the operating temperature range to guarantee reliability under expected thermal conditions.

RF Multiplexers Part Context

This device belongs to the DPX series of RF multiplexers produced by TDK Corporation. It is categorized under RF diplexers intended for wireless connectivity solutions. The component complements other passive RF elements used in modern communication hardware. Its design aligns with industry standards for miniaturized surface-mount technology components.

RF Multiplexers Replacement Considerations

The DPX165950DT-8126A1 serves as a related alternative within the same product family. Verify frequency band compatibility before substitution, as the alternative supports slightly different high-band ranges. Ensure package dimensions and pin configurations remain identical to maintain mechanical fit.
