6782-6165-03

Attenuators Overview

The Amphenol XMA 6782-6165-03 is a fixed RF attenuator module designed for high-frequency applications. It provides a nominal attenuation of 3 dB with an operating frequency range from 0 Hz to 65 GHz. The component features a 50 Ohm impedance and supports a power rating of 1 Watt. It utilizes a 1.85mm connector interface, configured as an in-line module with male-to-female gendering. The unit has a physical length of 22.35 mm and weighs 7 grams. The Voltage Standing Wave Ratio (VSWR) is specified at 1.65:1. This part is classified as active and is packaged in bulk.

Attenuators Feature Summary

• Supports ultra-wideband operation extending up to 65 GHz
• Utilizes precision 1.85mm coaxial connector interface
• Designed for non-cryogenic in-line signal conditioning

Attenuators Applications

• High-frequency test and measurement instrumentation
• Microwave and millimeter-wave circuit characterization
• Signal path loss compensation in RF systems

Attenuators Procurement Notes

Verify the specific datasheet version for the 6782-6165-03 model to confirm current manufacturing status and detailed electrical tolerances. Ensure that the 1.85mm mating connectors are compatible with the system design requirements. Confirm that the 1W power rating aligns with the operational thermal conditions. Check for any specific handling instructions regarding the bulk packaging format to prevent connector damage during installation.

Attenuators Selection Notes

Select this component when a fixed 3 dB attenuation is required within a 0 to 65 GHz bandwidth. The 1.85mm interface dictates compatibility with existing connector infrastructure. Consider the 1W power limit for maximum signal levels. The non-cryogenic designation indicates suitability for standard ambient temperature environments rather than extreme cold applications.

Attenuators Part Context

This attenuator belongs to the Amphenol XMA Omni Spectra series, which offers various frequency ratings including 18GHz, 26.5GHz, and 40GHz options. The 6782-6165-03 specifically targets the highest frequency tier at 65 GHz. Related variants include different attenuation values such as 30 dB models and cryogenic versions like the 6782-6165-03-CRYO, indicating a modular product family structure.

Attenuators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The 6782-6165-03-CRYO is a variant but serves cryogenic conditions, not a direct drop-in replacement for standard ambient use without thermal verification.
