DPX162170DT-8022B1

RF Multiplexers Overview

The DPX162170DT-8022B1 is a surface-mount RF diplexer manufactured by TDK Corporation, designed for signal conditioning in wireless communication systems. It operates within two distinct frequency bands: a low band ranging from 704MHz to 960MHz and a high band spanning 1.71GHz to 2.17GHz. The component utilizes SAW technology and is housed in a compact 0603 (1608 Metric) package with six PCB pads. Electrical specifications include minimum attenuation of 15.00dB for the low band and 20.00dB for the high band, ensuring effective signal isolation between the designated frequency ranges.

RF Multiplexers Feature Summary

• Integrates dual-band filtering capabilities within a single compact surface-mount device
• Utilizes Surface Acoustic Wave (SAW) technology for precise frequency selection
• Provides significant signal attenuation to isolate low and high frequency bands
• Designed for board mounting in space-constrained electronic assemblies

RF Multiplexers Applications

• Mobile phone transceiver modules requiring duplexed signal paths
• Wireless communication base station interfaces
• RF front-end assemblies for cellular network equipment
• Signal conditioning circuits in multi-standard radio devices

RF Multiplexers Procurement Notes

This component is officially listed as End-of-Life (EOL) or obsolete by the manufacturer. Verification of current availability should focus on remaining stock from authorized distributors or secondary market suppliers. Buyers must confirm the specific manufacturing date code and physical condition prior to purchase, as new production units are no longer available. Ensure that any sourced units match the original datasheet specifications exactly.

RF Multiplexers Selection Notes

Engineers selecting this part must verify compatibility with the target system's specific frequency requirements, particularly the 704MHz-960MHz and 1.71GHz-2.17GHz bands. The 0603 package footprint requires careful consideration of PCB layout constraints and soldering profiles suitable for small outline packages. Due to its discontinued status, alternative components with similar electrical characteristics and pin configurations should be evaluated for long-term supply chain stability.

RF Multiplexers Part Context

The DPX162170DT-8022B1 belongs to TDK's DPX series of RF multiplexers, which are specialized passive components used for separating or combining radio frequency signals. This series is characterized by its use of SAW filters integrated into diplexer architectures, allowing for efficient handling of multiple frequency bands in a single package. These components are critical for maintaining signal integrity in modern wireless infrastructure.
