765A-20

Attenuators Overview

The L3 Narda-MITEQ 765A-20 is a fixed RF attenuator module designed for high-power applications. It provides a nominal attenuation of 20 dB across a frequency range from DC to 5 GHz. The component features Type N male/female connectors and supports a maximum power handling capacity of 50 watts. Key electrical specifications include a VSWR of 1.20:1 maximum in the passband and an isolation of 300 dB. This ruggedized design ensures stable performance in demanding radio frequency environments.

Attenuators Feature Summary

• Fixed 20 dB attenuation value for precise signal level control
• High power handling capability up to 50 watts
• Broadband operation from DC to 5 GHz
• Robust Type N connector interface for secure mating

Attenuators Applications

• RF test and measurement equipment
• Telecommunications infrastructure systems
• Military and aerospace radar systems
• Satellite communication ground stations

Attenuators Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with the manufacturer or authorized distributor before procurement. Ensure that the connector gender configuration matches the system requirements, as Type N interfaces require precise alignment. Confirm thermal management capabilities are adequate for continuous 50W operation in the intended enclosure environment to prevent overheating.

Attenuators Selection Notes

Select this model when a fixed 20 dB reduction is required at frequencies up to 5 GHz with significant power handling needs. Compare against variable attenuators if adjustable levels are necessary. Consider the physical size and weight constraints of the assembly, as coaxial modules are bulkier than surface-mount alternatives. Validate impedance matching requirements to ensure compatibility with standard 50-ohm systems.

Attenuators Part Context

The 765A-20 belongs to the L3 Narda-MITEQ series of fixed coaxial attenuators. This family includes various attenuation values and frequency ranges tailored for different RF power levels. The 765A series specifically targets high-power applications, distinguishing itself from lower-power thin-film or chip-based attenuators used in consumer electronics.

Attenuators Replacement Considerations

Direct substitutes may include other 20 dB fixed attenuators from manufacturers like Mini-Circuits or Pasternack, provided they meet the 50W power rating and 5 GHz frequency limit. Verify connector type and flange dimensions for mechanical compatibility. Cross-reference VSWR and insertion loss specs to ensure equivalent signal integrity.
