DPX205850DT-9038A1-H

RF Multiplexers Overview

The DPX205850DT-9038A1-H is an LTCC diplexer manufactured by TDK Corporation, designed for signal conditioning in RF applications. It operates across two frequency bands: a low band of 2.4 GHz to 2.5 GHz and a high band of 5.15 GHz to 5.85 GHz. The component utilizes a surface-mount package with dimensions of 0805 (2.012 mm x 1.25 mm) and features six contact pads. Electrical specifications include insertion losses of 2.4 dB and 1.5 dB for the respective bands, with attenuation reaching up to 39.10 dB in the low band and 31.20 dB in the high band. The device supports a wide operating temperature range from -40°C to +80°C and complies with RoHS3 standards.
