DPX165850DT-8086A1

RF Multiplexers Overview

The DPX165850DT-8086A1 is a multilayer SAW diplexer manufactured by TDK Corporation, designed for signal conditioning in RF applications. It operates with two distinct frequency bands: a low band spanning 698 MHz to 2.69 GHz and a high band covering 3.4 GHz to 5.85 GHz. The device features a 50 Ohm impedance and utilizes an SMD/SMT surface mount package in the 0603 (1608 metric) footprint with six pads. Key electrical parameters include an insertion loss of 0.66 dB, minimum attenuation of 20.00 dB for the low band and 18.00 dB for the high band, and return loss of 9.54 dB for both bands. It functions within a temperature range of -40°C to +85°C.

RF Multiplexers Feature Summary

• Integrates dual-band filtering capabilities into a compact multilayer SAW structure
• Provides high isolation between adjacent frequency bands to minimize interference
• Supports surface mount assembly for automated PCB manufacturing processes

RF Multiplexers Applications

• Mobile phone front-end modules
• Smartphone RF signal routing
• Wireless communication devices requiring band separation

RF Multiplexers Procurement Notes

Verify component authenticity through authorized TDK distributors or certified suppliers. Confirm RoHS compliance status and check for specific packaging variants such as cut tape or reel options. Ensure the received part matches the exact DPX165850DT-8086A1 designation to avoid functional mismatches in RF circuit designs.

RF Multiplexers Selection Notes

Select this component when designing circuits requiring simultaneous operation in sub-3 GHz and 5 GHz ranges. The 0603 package size suits space-constrained mobile layouts. Verify that the specified attenuation and insertion loss values meet system noise floor requirements. Consider thermal stability limits if operating near extreme environmental boundaries.
