NAT-20DC+

Overview

The NAT-20DC+ is a fixed attenuator from Mini-Circuits designed for RF and microwave applications. It provides a nominal attenuation of 20 dB with a maximum deviation of 1 dB across its operational bandwidth. The component operates within a frequency range of 500 MHz to 2.3 GHz and maintains a 50 Ohm impedance. It features N-type connectors and supports DC passing capabilities. The power rating is specified at 400 mW, and it functions reliably within a temperature range of -55°C to +85°C.

Feature Summary

• Provides precise 20 dB fixed signal attenuation
• Supports direct current (DC) passage through the circuit
• Utilizes robust N-type connector interface
• Maintains stable performance in wide temperature environments

Applications

• RF signal level control in wireless communication systems
• Impedance matching in test and measurement setups
• Signal conditioning in microwave receiver chains
• Attenuation stages in broadband amplifier circuits

Procurement Notes

Verify the specific datasheet version ED-10191 for accurate electrical parameters before integration. Confirm that the N-type connector gender and cable assembly requirements match your system design. Ensure the 400 mW power rating aligns with peak signal levels to prevent thermal damage. Check RoHS compliance status if environmental regulations apply to your manufacturing process.

Selection Notes

Select this model when a fixed 20 dB reduction is required between 500 MHz and 2.3 GHz. Consider the N-type interface compatibility with existing cabling infrastructure. Evaluate the 400 mW power handling against maximum input signals. Compare against other NAT series variants if different attenuation values or frequency ranges are needed for the specific application.

Part Context

This component belongs to the NAT series of fixed attenuators manufactured by Mini-Circuits. These devices are engineered for interconnect applications requiring reliable signal attenuation. The series typically offers various attenuation values and frequency ranges to suit diverse RF system requirements while maintaining consistent impedance characteristics.

Replacement Considerations

NAT-20DC is the non-RoHS compliant predecessor variant. Verify connector specifications and mounting requirements when substituting. Ensure frequency coverage meets the 500 MHz to 2.3 GHz requirement.
