DPX165950DT-8045A1

RF Multiplexers Overview

The TDK DPX165950DT-8045A1 is an LTCC diplexer designed for signal conditioning in RF front-end systems. It operates with a low band of 2.4–2.5 GHz and a high band of 4.9–5.95 GHz, supporting bandwidths of 100 MHz and 1050 MHz respectively. The component features a 50 Ohm impedance and utilizes SMD/SMT termination for board mounting. Housed in a compact 0603 (1608 metric) package with six terminals, it functions within a temperature range of -40°C to +85°C. Insertion losses are specified at 0.35 dB and 0.6 dB for the respective bands.
