DPX165950DT-8126A1

RF Multiplexers Overview

The DPX165950DT-8126A1 is an RF diplexer manufactured by TDK Corporation, designed for signal conditioning in wireless applications. It operates with a low band frequency range of 2.4 GHz to 2.5 GHz and a high band range of 4.9 GHz to 5.95 GHz. The component features a center frequency of 2.45 GHz for the lower band and 5.425 GHz for the upper band. Insertion loss is specified at 0.3 dB for the low band and 0.37 dB for the high band. Return loss values are 21.5 dB for the low band and 16.6 dB for the high band. The device utilizes a 50 Ohm impedance and is housed in a 0603 (1608 metric) surface-mount package with six printed circuit board pads. It supports a standard factory packaging quantity of 4,000 units.
