LNA-20-02000800-43-25P

Overview

The LNA-20-02000800-43-25P is a low-noise amplifier module manufactured by L3 Narda-MITEQ, designed for VSAT applications. It operates within a frequency range of 2 GHz to 8 GHz. The device provides a typical gain of 25 dB with a noise figure of 4.3 dB. It delivers an output power at 1 dB compression (P1dB) of 20 dBm and requires a supply voltage of 15 VDC with a current consumption of approximately 225 mA. The component is housed in a shielded module package equipped with SMA connectors, ensuring stable performance in satellite communication systems.

Feature Summary

• Provides high-gain amplification suitable for weak signal reception in satellite downlinks
• Features ultra-low noise characteristics to preserve signal integrity in the front-end chain
• Includes internal voltage regulation for stable operation under varying supply conditions
• Offers unconditional stability across various load impedances without oscillation risks

Applications

• VSAT satellite communication ground station receivers
• Satellite navigation receiver front-ends (GPS, GLONASS, Galileo)
• Microwave radio link receiving terminals
• Radar system signal processing chains

Procurement Notes

Verify the specific suffix 'DG' or standard packaging against the official L3Harris Narda-MITEQ datasheet to ensure compatibility with required environmental ratings. Confirm that the SMA connector type matches the system interface requirements. Check for RoHS compliance status if restricted substances are a concern for the target application. Ensure the supply voltage tolerance aligns with the 15V DC requirement specified in the technical documentation.

Selection Notes

Select this component when a wide bandwidth covering 2 to 8 GHz is required alongside low noise performance. It is appropriate for systems prioritizing signal-to-noise ratio improvement in the L-band through C-band ranges. Consider the module form factor for ease of integration into existing RF assemblies. Evaluate the thermal management capabilities if operating near the upper temperature limits defined in the specifications.

Part Context

This model belongs to the LNA-20 series of low-noise amplifiers from L3 Narda-MITEQ, now part of L3Harris Technologies. The series is engineered for robust performance in aerospace and defense communications. These modules are characterized by their reliability in harsh environments and consistent electrical parameters over temperature variations, making them standard choices for critical satellite infrastructure.

Replacement Considerations

Direct substitutes may include other LNA-20 series variants with adjusted frequency or gain parameters, such as LNA-20-02000400-25-20P for narrower bandwidth needs. Cross-reference pinouts and mechanical dimensions before substitution. Verify that alternative models meet the same noise figure and P1dB requirements to maintain system performance integrity.
