Attenuators

Product catalog summary

Introduction
Attenuators are linear passive components used to reduce input power in coaxial lines by a specific ratio, expressed logarithmically. They are applicable in Test & Measurement, defense, space, and thermal vacuum applications.

Features and Benefits
Attenuators provide broadband capabilities, options for low, medium, and high power, and low VSWR, ensuring high repeatability.

Low Power Attenuators
- Power: 0.5 to 2 Watts
- Connectors: BNC, QN, N, SMA, SMA 2.9, SMB, TNC, 7/16
- Frequency Range: DC to 40 GHz
- Attenuation Range: 0 to 60 dB

Medium Power Attenuators
- Power: 3 to 50 Watts
- Connectors: BNC, N, SMA, TNC, 7/16
- Frequency Range: DC to 18 GHz
- Attenuation Range: 0 to 30 dB

High Power Attenuators
- Power: 80 to 100 Watts
- Connectors: N, SMA, TNC, 7/16
- Frequency Range: DC to 6 GHz
- Attenuation Range: 0 to 20 dB

Attenuators for Space/Thermal Vacuum Applications
Consultation is required for details.

Technical Specifications
Connectors such as 7/16, BNC, N, QMA, QN, SMA, SMA 2.9, SMB, SMC, and TNC are detailed with frequency ranges, VSWR max, return loss min, power ratings, nominal attenuation, and part numbers. Specific attenuation values and deviations are provided for each connector type.

- R417 9xx 128 and R417 9xx 138 for attenuation values 03, 06, 10, and 20 dB.

Catalog excerpts

Our Most Important Connection is with You.™ Introduction Attenuators are linear passive bidirectional transition line components designed to be inserted between two coaxial lines in order to reduce the input power in a matched system by a predetermined ratio. This ratio is expressed in logarithmic terms. 3 dB as a power ratio is 2, 6 dB is 4, 20 dB is 100 and 30 dB is 1000 etc… Attenuators are applied in Test & Measurement, defense, space and thermal vacuum applications. FEATURES • Broadband • Low, Medium and High power • Low VSWR BENEFITS • High repeatability LOW POWER ATTENUATORS Power Frequency range Attenuation range MEDIUM POWER ATTENUATORS Power Connectors Frequency range Attenuation range HIGH POWER ATTENUATORS Power Connectors Frequency range Attenuation range ATTENUATORS FOR SPACE / THERMAL VACUUM APPLICATIONS Power Frequency range Attenuation range Attenuators for Space / thermal vacum applications are not detailled in this document.
