DPX162690DT-8058A1

RF Multiplexers Overview

The DPX162690DT-8058A1 is a surface-mount RF diplexer manufactured by TDK Corporation, designed for signal conditioning in wireless communication systems. It operates within two distinct frequency bands: a low band ranging from 704MHz to 960MHz and a high band spanning 1.57GHz to 2.69GHz. The component features an attenuation of 23.00dB minimum in the low band and 25.00dB minimum in the high band, with return losses specified at 12.0dB for both bands. Housed in a compact 0603 (1608 metric) package with six printed circuit board pads, it supports SMD/SMT installation and functions reliably across an operating temperature range of -40°C to +85°C.
