DPX162500DT-8114C1

RF Multiplexers Overview

The DPX162500DT-8114C1 is an RF diplexer manufactured by TDK Corporation, designed for signal conditioning in wireless communication systems. It operates with a low frequency band of 1.565 GHz to 1.585 GHz and a high frequency band of 2.4 GHz to 2.5 GHz. The component features a minimum attenuation of 20.00 dB for both bands, with maximum attenuation values of 25.80 dB and 27.90 dB respectively. Return loss is specified at 9.54 dB for both the low and high frequency bands. It utilizes a surface mount technology (SMD/SMT) package in the 0603 (1608 Metric) footprint with four pads. The device supports a standard packaging quantity of 4,000 units per reel.
