M3933/25-33N

Overview

The M3933/25-33N is a coaxial attenuator manufactured by Amphenol SV Microwave, belonging to the SMA series. It features a male-to-female connector configuration with a nominal impedance of 50 ohms. The component provides an attenuation value of 7 dB and operates within a frequency range up to 18 GHz. It is designed for non-screened applications and supports a maximum operating temperature of +165°C and a minimum of -65°C.

Feature Summary

• Provides fixed 7 dB signal attenuation in a compact coaxial form factor
• Supports high-frequency operation up to 18 GHz with 50 ohm impedance
• Constructed with SMA male-to-female interface for reliable interconnection

Applications

• RF test and measurement instrumentation requiring precise signal reduction
• Military and aerospace communication systems adhering to MIL-spec standards
• High-frequency circuit testing environments needing stable attenuation

Procurement Notes

Verify the specific datasheet version for the M3933/25-33N to confirm current manufacturing status and detailed electrical tolerances. Ensure that the non-screened construction aligns with your system's electromagnetic interference requirements. Cross-reference the SMA gender configuration to guarantee compatibility with existing mating connectors in your assembly.

Selection Notes

Select this component when a fixed 7 dB attenuation is required at frequencies up to 18 GHz. The SMA interface ensures broad compatibility with standard RF infrastructure. Consider the non-screened design if shielding is provided elsewhere in the system architecture. Verify thermal ratings against the operational environment limits to ensure reliability under extreme conditions.

Part Context

This part belongs to the M3933 series of RF military specification connectors and attenuators produced by Amphenol SV Microwave. The series offers various attenuation values and connector types, including SMA and 2.92mm configurations. These components are engineered for rugged performance in demanding electronic applications.

Replacement Considerations

Compatible substitutes include other M3933/25-XXN variants from Amphenol SV Microwave with different attenuation values, such as the M3933/25-31N (5 dB) or M3933/25-27N (1 dB). Ensure the replacement maintains the same SMA male-to-female orientation and 50 ohm impedance characteristics.
