ATT-0451-03-SMA-02 is listed in the Attenuators range at ChipApex. The manufacturer field lists Cinch Connectivity Solutions Midwest Microwave. Its product description is RF ATTENUATOR 3DB SMA MODULE. Review the specifications below when checking this part for your BOM.
The ATT-0451-03-SMA-02 is a fixed RF attenuator module manufactured by Cinch Connectivity Solutions under the Midwest Microwave brand. It provides a nominal attenuation of 3 dB across a frequency range from DC to 18 GHz. The component utilizes SMA connectors for interconnection and is rated for a power handling capacity of 2 Watts. Constructed with a stainless steel body, it is designed for reliable performance in embedded applications within the microwave spectrum.
Verify the specific datasheet version and mechanical drawings prior to procurement. Confirm that the SMA connector gender and mounting requirements align with the system design. Ensure the 2W power rating and 18GHz frequency limit meet the operational specifications. Check for any recent updates to the product qualification status or environmental compliance documentation.
Select this model when a precise 3 dB reduction is required at frequencies extending to 18 GHz. The SMA interface offers compatibility with standard coaxial systems. Consider the 2W power limit and stainless steel durability for rugged environments. Evaluate alternative attenuation values if the signal level requires different adjustment.
This part belongs to the ATT-0451 series of connectorized attenuators. The series includes variants with different attenuation levels, such as 0 dB and other fixed values, all sharing similar SMA interfaces and frequency ranges. The numbering convention typically indicates the specific attenuation value within the series.
Direct substitutes include ATT-0451-00-SMA-02 (0 dB) and ATT-0451-03-SMA-07. Verify connector type and attenuation value before substitution.
