DPX105950DT-6012A1

RF Multiplexers Overview

The DPX105950DT-6012A1 is a signal conditioning LTCC diplexer manufactured by TDK Corporation. It operates within the frequency ranges of 2.3 GHz to 2.5 GHz and 4.9 GHz to 5.95 GHz, designed for surface mount installation in a 0402 (1005 metric) package with four pads. The device maintains a characteristic impedance of 50 Ohms and functions reliably across an operating temperature range from -40°C to +85°C. Key electrical specifications include a minimum attenuation of 30.00 dB in the low band and 20.00 dB in the high band. Additionally, it provides a return loss of 10.0 dB for both frequency bands, ensuring efficient signal transmission.

RF Multiplexers Feature Summary
