LAT-5+

Overview

The LAT-5+ is a fixed attenuator from Mini-Circuits designed for RF and microwave applications. It provides a nominal attenuation of 5 dB across a wide frequency range from DC to 2.5 GHz. The component operates with a characteristic impedance of 50 Ohms and has a maximum power handling capacity of 500 mW. It utilizes a TO-253-4 surface-mount package, ensuring reliable performance in high-frequency circuits. Typical insertion loss remains stable around 5.15 dB at lower frequencies, increasing slightly to approximately 5.25 dB at 100 MHz, while maintaining an isolation of over 40 dB.

Feature Summary

• Wideband operation covering DC to 2.5 GHz
• Excellent voltage standing wave ratio (VSWR) for signal integrity
• Fixed 5 dB attenuation value
• Surface-mount TO-253-4 package design

Applications

• RF signal level control in communication systems
• Impedance matching in test and measurement equipment

Procurement Notes

Verify the specific part number suffix against official Mini-Circuits documentation to ensure correct specifications. Confirm that the procurement channel sources components directly from authorized distributors or the manufacturer to guarantee authenticity. Check the datasheet for any recent updates regarding pin configuration or thermal characteristics before finalizing orders.

Selection Notes

Select the LAT-5+ when a fixed 5 dB attenuation is required within a DC to 2.5 GHz bandwidth. Consider its 500 mW power rating for appropriate signal levels. The TO-253-4 package is suitable for surface-mount assembly processes. Ensure the application environment supports the specified operating temperature range and impedance requirements for optimal performance.

Part Context

The LAT-5+ belongs to Mini-Circuits' line of fixed attenuators, which are essential passive components in RF circuit design. These devices provide precise signal reduction without introducing significant distortion. The series includes various attenuation values and frequency ranges, catering to diverse microwave and radio frequency engineering needs for system stability and protection.

Replacement Considerations

Consult Mini-Circuits official substitution guides for compatible alternatives. Verify that any substitute matches the 5 dB attenuation, 50 Ohm impedance, and DC to 2.5 GHz frequency range. Ensure the replacement component fits the TO-253-4 footprint if space constraints are critical.
