ATT-0290-04-SMA-02

Attenuators Overview

The ATT-0290-04-SMA-02 is a fixed coaxial attenuator manufactured by Midwest Microwave, part of Cinch Connectivity Solutions. It provides a nominal attenuation of 4 dB with a maximum operating frequency of 18 GHz and a minimum frequency of DC (0 MHz). The device supports a maximum continuous wave input power of 2 Watts (33.01 dBm) and maintains a maximum voltage standing wave ratio (VSWR) of 1.2. Constructed from stainless steel, it operates within a temperature range of -65 °C to 125 °C.

Attenuators Feature Summary

• Provides precise 4 dB signal attenuation for RF applications
• Operates across a wide frequency spectrum from DC to 18 GHz
• Features SMA male-to-female interconnect configuration
• Constructed from stainless steel for durability

Attenuators Applications

• RF signal level control in microwave systems
• Test and measurement equipment calibration
• Communication system signal conditioning

Attenuators Procurement Notes

Verify the specific manufacturer designation, as this component is associated with both Midwest Microwave and Cinch Connectivity Solutions. Confirm that the SMA connector gender matches the required male-to-female interface. Ensure the 2W power rating and 18 GHz frequency limit align with the operational requirements of the target circuit environment.

Attenuators Selection Notes

Select this model when a fixed 4 dB attenuation is required within an 18 GHz bandwidth. The stainless steel construction and SMA connectors make it suitable for robust RF environments. Verify that the 2W power handling capacity meets the system's maximum input power specifications before integration.

Attenuators Part Context

This component belongs to the ATT-0290 series of fixed attenuators. It shares design characteristics with similar models such as the ATT-0290-02-SMA-02, which offers 2 dB attenuation, and the ATT-0290-04-HEX-02, which utilizes hexagonal connectors instead of SMA interfaces.

Attenuators Replacement Considerations

The ATT-0290-02-SMA-02 serves as a functional substitute if a different attenuation value is acceptable. For non-SMA interfaces, the ATT-0290-04-HEX-02 is a related alternative within the same product family.
