DPX205850DT-9043B1BR

RF Multiplexers Overview

The DPX205850DT-9043B1BR is a multilayer diplexer manufactured by TDK Corporation, utilizing low-temperature co-fired ceramic (LTCC) technology. It operates within the 2.4GHz to 2.5GHz and 5.15GHz to 5.85GHz frequency bands. The component features a minimum isolation of 20.00dB for the high band and 23.00dB for the low band, with maximum attenuation reaching 31.20dB and 39.10dB respectively. Return loss is specified at 10.0dB for both bands. It is housed in an 0805 (2012 metric) surface-mount package containing six printed circuit board pads.

RF Multiplexers Feature Summary

• Utilizes LTCC technology for low insertion loss and latency performance
