DPX202170DT-4049A1

RF Multiplexers Overview

The DPX202170DT-4049A1 is an RF diplexer manufactured by TDK Corporation, designed for surface-mount integration in compact electronic systems. It operates across two distinct frequency bands: a low band ranging from 824 MHz to 960 MHz and a high band spanning 1.71 GHz to 2.17 GHz. The component provides minimum attenuation of 15 dB for the low band and 20 dB for the high band, with maximum attenuation reaching 23 dB in the high band. Return loss specifications are 20 dB for the low band and 14 dB for the high band. Packaged in a 0805 (2012 Metric) footprint with six PCB pads, it supports tape-and-reel handling.
