DPX162690DT-8022B2

RF Multiplexers Overview

The DPX162690DT-8022B2 is a multilayer LTCC diplexer manufactured by TDK Corporation, designed for RF signal conditioning in compact electronic systems. It operates with two distinct frequency bands: a low band ranging from 704MHz to 960MHz and a high band spanning 1.71GHz to 2.69GHz. The component features a 0603 (1608 metric) surface-mount package with six printed circuit board pads. Key electrical specifications include a minimum attenuation of 20.00dB in the low band, with return losses measured at 19.7dB for the low band and 9.9dB for the high band. The device maintains a standard impedance of 50 Ohms and supports an operating temperature range starting at -40°C.

RF Multiplexers Feature Summary

• Integrates dual-band filtering capabilities within a single compact LTCC structure
• Provides significant signal isolation through specified attenuation levels
• Utilizes surface-mount technology for automated assembly integration

RF Multiplexers Applications

• RF cellular communication modules requiring duplexing functions
• Wireless connectivity subsystems utilizing specified frequency ranges
• Mobile device front-end signal processing circuits

RF Multiplexers Procurement Notes

Verify component authenticity against official TDK documentation due to potential availability variations. Confirm that the specific suffix matches the required frequency parameters. Check current lifecycle status as components may transition to end-of-life phases. Ensure storage conditions comply with moisture sensitivity levels for surface-mount devices. Validate compatibility with existing PCB footprint designs before finalizing procurement orders.

RF Multiplexers Selection Notes

Choose this component when space-constrained designs require integrated dual-band filtering without discrete solutions. Evaluate the specific return loss requirements for both frequency bands to ensure system performance meets design goals. Consider the 0603 package dimensions for layout constraints. Assess thermal management needs given the -40°C lower operating limit. Verify impedance matching requirements align with the 50 Ohm specification for optimal signal transmission.
