DPX205850DT-4155A1

RF Multiplexers Overview

The TDK DPX205850DT-4155A1 is an LTCC diplexer designed for signal conditioning in RF applications. It operates across two distinct frequency bands: a low band ranging from 700 MHz to 1.99 GHz and a high band spanning 2.4 GHz to 5.85 GHz. The component utilizes a surface-mount package with dimensions of 2.00 mm length, 1.25 mm width, and 0.90 mm thickness, conforming to the 0805 (2012 metric) footprint with six PCB pads. It supports an operating temperature range from -40°C to +85°C.
