ATT-0640-20-29M-02

Attenuators Overview

The ATT-0640-20-29M-02 is an RF attenuator manufactured by Midwest Microwave, a division of Cinch Connectivity Solutions. This component provides a fixed attenuation value of 20 dB across a frequency range of DC to 40 GHz. It utilizes a 2.92mm (K-type) connector interface, supporting both male and female configurations for versatile interconnect applications. The device is rated for a maximum power handling capacity of 1 Watt. Designed for high-frequency performance, it operates within a temperature range of -55°C to +125°C. The unit is packaged in bulk format, suitable for integration into custom cable assemblies or modular RF systems requiring precise signal reduction at microwave frequencies.

Attenuators Procurement Notes

Verify the specific connector gender configuration required for your assembly, as the series supports both male and female variants. Confirm that the 1W power rating aligns with your system's peak and average power levels. Ensure the 2.92mm interface compatibility with existing PCB or cable connections. Check for any specific environmental qualification requirements if deploying in harsh conditions beyond standard operating temperatures.

Attenuators Selection Notes

Select this model when a precise 20 dB attenuation is needed at frequencies extending to 40 GHz. The 2.92mm interface offers superior performance over SMA types at these higher frequencies. Consider the 1W power limit when designing for high-power transmission lines. Evaluate the bulk packaging option against automated assembly needs versus individual unit handling requirements for prototyping.

Attenuators Part Context

This component belongs to the ATT-0640 series from Midwest Microwave, specializing in semi-rigid and flexible cable assemblies with integrated components. The series targets demanding applications in military, aerospace, and telecommunications sectors. Midwest Microwave products are known for their reliability in harsh environments and support for complex RF engineering solutions across wide bandwidths.

Attenuators Replacement Considerations

Direct substitutes may include other 20dB 2.92mm attenuators from manufacturers like Johnson Components or Semflex, provided they meet the 40GHz and 1W specifications. Verify dimensional tolerances and mating force characteristics to ensure mechanical interchangeability without modifying the host assembly.
