DPX205850DT-4154B1

RF Multiplexers Overview

The DPX205850DT-4154B1 is a multilayer diplexer manufactured by TDK Corporation, designed for RF front-end applications. It operates within the frequency bands of 174MHz to 1.58GHz and 2.4GHz to 5.85GHz. The device features a low-band attenuation range of 13.00dB to 28.00dB and a high-band attenuation range of 9.00dB to 28.00dB. Return loss specifications are 12.0dB for the low band and 28.0dB for the high band. It utilizes a surface-mount package in the 0805 (2012 metric) dimension with six PCB pads.
