M3933/30-05S

Overview

The M3933/30-05S is an RF attenuator manufactured by Amphenol SV Microwave, designed for high-frequency applications up to 32 GHz. It features a 2.92mm female-to-male connector configuration with a nominal attenuation of 2 dB and a 50 Ohm impedance. The component supports a power rating of 2 W and operates within a temperature range of -65°C to +165°C. It is classified as a screened military specification device, ensuring reliability in demanding environments.

Feature Summary

• Provides precise signal attenuation for RF systems operating at frequencies up to 32 GHz.
• Constructed with durable materials suitable for extreme thermal conditions ranging from -65°C to +165°C.
• Features a screened design to maintain signal integrity and reduce electromagnetic interference.

Applications

• Military radar systems requiring stable signal levels at high frequencies.
• Test and measurement equipment needing calibrated attenuation in the 2.92mm format.
• Avionics communication links operating under strict environmental constraints.

Procurement Notes

Verify the specific screening requirements against your system's environmental standards before procurement. Confirm that the 2.92mm interface compatibility matches existing test fixtures or cable assemblies. Ensure the 2 W power handling capacity aligns with peak signal levels in your application to prevent component damage during operation.

Selection Notes

Select this model when a fixed 2 dB attenuation is required in a 2.92mm form factor. Consider the wide operating temperature range if the deployment environment involves significant thermal fluctuations. Verify that the male-female orientation fits the intended interconnect topology without requiring additional adapters.

Part Context

This component belongs to the M3933 series of RF attenuators, which are engineered for military and aerospace use. The series offers various attenuation values and connector types, all adhering to stringent performance standards. The M3933/30-05S specifically addresses needs for moderate attenuation in high-frequency scenarios.

Replacement Considerations

M3933/30-05N is listed as a parameter-equivalent substitute. Verify mechanical and electrical compatibility before substitution. Other manufacturers may offer similar specifications but require validation of interface dimensions and frequency response curves.
