RF Multiplexers Procurement Notes

Verify the current lifecycle status before procurement, as this component is listed as obsolete in available distributor records. Confirm availability through authorized channels or secondary markets if immediate production use is required. Ensure that the specific suffix matches the required frequency band specifications, as variations may exist within the product family. Cross-reference the datasheet for any updated manufacturing constraints or alternative part numbers recommended by the manufacturer.

RF Multiplexers Selection Notes

Select this component when designing circuits requiring separation of 2.4 GHz and 5 GHz signals in a small form factor. The 0805 package size is suitable for space-constrained PCB layouts. Ensure the system impedance matches the 50 Ohm specification to maintain signal integrity. Consider the thermal operating range of -40°C to +85°C for environmental compatibility. Verify that the attenuation requirements align with the 20.00 dB minimum specification for adequate band isolation.

RF Multiplexers Part Context

This diplexer belongs to the DPX series of signal conditioning components from Pulse Electronics. It is part of a broader portfolio of RF filters and multiplexers designed for wireless communication devices. The series typically includes various package sizes and frequency configurations to support different Wi-Fi and Bluetooth standards.
