M3933/30-33N

Overview

The M3933/30-33N is a fixed RF attenuator from Amphenol SV Microwave, part of the 2.92mm series. It provides 20 dB attenuation with a 50 Ohm impedance across a frequency range of DC to 32 GHz. The device features SMA male-to-female connectors and supports a power rating of 2 W. It operates within a temperature range of -65°C to +165°C and is packaged in bulk.

Feature Summary

• Provides precise 20 dB signal attenuation for RF applications
• Supports high-frequency operation up to 32 GHz
• Designed for extreme environmental conditions with wide temperature tolerance

Applications

• Satellite microwave circuit power level adjustment
• RF test and measurement instrumentation
• Military and aerospace communication systems

Procurement Notes

Verify the specific connector gender configuration against project requirements, as datasheets may list variations such as Jack-to-Plug or Plug-to-Jack for this series. Confirm that the 2 W power rating aligns with peak signal levels. Ensure compatibility with 50 Ohm system impedance to prevent signal reflection issues during integration.

Selection Notes

Select this component when a fixed 20 dB attenuation is required at frequencies extending to 32 GHz. The 2.92mm series offers superior performance over standard SMA up to higher frequencies. Consider the ruggedized construction for environments requiring operation between -65°C and +165°C.

Part Context

This model belongs to the M3933 family of space attenuators designed by Amphenol SV Microwave. These components are engineered for military and aerospace use, offering reliable attenuation in harsh environments. The 2.92mm interface ensures low VSWR and consistent performance in high-frequency RF paths.

Replacement Considerations

Compatible substitutes include M3933/30-33S (screened version) and other M3933/30 variants with matching 20 dB attenuation and 32 GHz frequency limits. Verify connector gender and screening requirements before substitution.
