AM465S146

Overview

The AM465S146 is a fixed attenuator manufactured by Anatech Electronics Inc., designed for microwave applications. It features a standard SMA female connector interface, ensuring compatibility with common RF test and measurement equipment. The device operates within a frequency range of DC to 18 GHz, providing stable attenuation performance across this broad spectrum. Constructed with precision internal components, it maintains low voltage standing wave ratio (VSWR) to minimize signal reflection. The unit is rated for a power handling capacity suitable for typical laboratory environments, offering reliable signal reduction without distortion or thermal instability during continuous operation.

Feature Summary

• Provides precise fixed attenuation values for signal level control in RF systems
• Utilizes SMA female connectors for secure and repeatable mating connections
• Engineered for consistent performance across a wide microwave frequency bandwidth
• Maintains low VSWR to preserve signal integrity and minimize reflections

Applications

• RF test and measurement setups requiring known signal reduction
• Protecting sensitive receiver inputs from high-power signals
• Impedance matching networks in microwave circuits
• Calibration standards for vector network analyzers

Procurement Notes

Verify the specific attenuation value required for your application, as Anatech may offer variants within the AM465 series. Confirm connector type and gender match your existing infrastructure. Request the latest datasheet to validate frequency response and power ratings against your operational limits. Ensure environmental specifications meet your deployment conditions. Cross-reference part numbers with official Anatech documentation to avoid substitution errors.

Selection Notes

Select this component when a fixed, precise attenuation value is needed between DC and 18 GHz. Consider the SMA interface if it aligns with your system's connector standards. Evaluate power handling requirements to ensure the device can dissipate heat effectively under maximum load. Compare VSWR specifications against system tolerance levels. Verify that the physical size fits within your enclosure constraints.

Part Context

Anatech Electronics specializes in passive microwave components, including attenuators, couplers, and filters. The AM465 series represents their line of precision fixed attenuators designed for general-purpose RF applications.
