28AS102-K30S3

Overview

The Rosenberger 28AS102-K30S3 is a connectorized attenuator designed for interconnect applications. It operates within the SMA frequency range, supporting frequencies from DC up to 18 GHz. The component features a nominal attenuation value of 30 dB and maintains a characteristic impedance of 50 Ohms. Constructed with SMA plug and jack connectors, it is rated for a power handling capacity of 2 Watts. This device serves as a precision passive RF component for signal level adjustment in high-frequency circuits.

Feature Summary

• Provides precise 30 dB signal attenuation for RF circuit management
• Operates reliably across the full SMA frequency spectrum up to 18 GHz
• Features robust 50 Ohm impedance matching for standard transmission lines
• Supports continuous power loads of 2 Watts for stable performance

Applications

• RF test and measurement equipment signal conditioning
• Wireless communication system power level control
• Microwave circuit calibration and verification setups
• Laboratory instrumentation signal path attenuation

Procurement Notes

Verify the specific model designation against official Rosenberger documentation to ensure compatibility with required SMA interfaces and 50 Ohm systems. Confirm that the 2 Watt power rating and 30 dB attenuation values align with your design specifications. Check for any updated RoHS compliance details or manufacturing status changes directly from the manufacturer before finalizing procurement decisions.

Selection Notes

Select this component when a fixed 30 dB attenuation is required within the SMA frequency band. Ensure the application environment supports the 2 Watt power handling capability without exceeding thermal limits. Verify that the SMA plug-to-jack configuration matches the existing cable assembly or fixture interfaces. Consider environmental factors such as operating temperature ranges if deployed in non-standard conditions.

Part Context

This part belongs to the Rosenberger series of connectorized attenuators, specifically tailored for interconnect solutions. It complements other models like the 32AS102-K30S3 and 02AS102-K10S4, offering standardized attenuation values across different connector types. These components are integral to maintaining signal integrity in high-frequency electronic systems requiring precise power reduction.

Replacement Considerations

Direct substitutes may include other Rosenberger SMA attenuators with identical 30 dB attenuation and 50 Ohm impedance, such as variants within the same product family. Ensure any replacement maintains the same SMA connector gender configuration and power rating. Cross-reference technical datasheets to verify frequency response and physical dimensions match the original design requirements.
