LAT-2+

Overview

The Mini-Circuits LAT-2+ is a miniature surface mount fixed attenuator designed for RF applications. It provides a nominal attenuation of 2 dB with a frequency range from DC to 2500 MHz. The component operates at a 50 Ohm impedance and handles up to 500 mW of power. It features a maximum VSWR of 1.6 and functions within an ambient temperature range of -55°C to +85°C. Packaged in the STO-143-4 SMD form factor, it ensures reliable signal level control in compact circuit designs.

Feature Summary

• Provides precise 2 dB fixed attenuation across a wideband DC to 2.5 GHz spectrum
• Engineered for high reliability with excellent voltage standing wave ratio performance
• Utilizes a compact surface mount package suitable for automated PCB assembly

Applications

• RF signal level adjustment in communication systems
• Impedance matching networks requiring specific attenuation values
• Test and measurement equipment calibration circuits

Procurement Notes

Verify the exact part number suffix against official Mini-Circuits documentation to ensure correct specifications. Confirm that the STO-143-4 package dimensions align with your PCB footprint requirements. Check the latest datasheet for updated thermal ratings and power handling capabilities before finalizing procurement orders.

Selection Notes

Select this component when a stable 2 dB attenuation is required within the S-band frequency range. Ensure the design accommodates the specified 500 mW power rating and operating temperature limits. Consider the surface mount profile for integration into space-constrained microwave assemblies.

Part Context

This component belongs to the LAT series of miniature fixed attenuators manufactured by Mini-Circuits. These devices are widely used in RF and microwave engineering to manage signal strength without introducing significant distortion. The LAT-2+ specifically addresses needs for low-loss, high-isolation attenuation in dense electronic layouts.

Replacement Considerations

Consult official Mini-Circuits substitution guides for verified equivalent models. Cross-reference electrical parameters such as attenuation tolerance, frequency range, and power handling to ensure functional compatibility during replacement scenarios.
