LNA-40-00100800-20-15P

Overview

The LNA-40-00100800-20-15P is a low-noise amplifier module from the L3 Narda-MITEQ LNA series, designed for VSAT applications. It operates within a frequency range of 100 MHz to 8 GHz. The device provides a minimum gain of 40 dB with a noise figure of 4 dB. Key electrical specifications include a P1dB output power of 20 dBm and a supply voltage of +15 VDC. Typical operating current is 350 mA. The unit features SMA connectors, a 50 Ω impedance, and a VSWR of 2:1. It is housed in a module package suitable for integration into RF systems.

Feature Summary

• Provides high gain of 40 dB across a wide 100 MHz to 8 GHz bandwidth
• Optimized for low noise performance with a 4 dB noise figure
• Features internal voltage regulation for stable DC power management
• Ensures unconditional stability under various load conditions

Applications

• VSAT satellite communication ground station receive links
• RF and microwave signal amplification chains
• Wireless communication equipment front-end stages
• Test and measurement instrumentation signal conditioning

Procurement Notes

Verify the specific part number against official L3 Narda-MITEQ documentation to confirm pinout and connector orientation. Ensure that the +15 VDC supply requirements and thermal dissipation capabilities align with the target system design. Cross-reference datasheet revisions to validate performance parameters such as gain flatness and noise figure consistency.

Selection Notes

Select this component when a wideband 100 MHz to 8 GHz coverage is required alongside high gain. Consider the 4 dB noise figure for sensitivity-critical receive paths. Evaluate the 20 dBm P1dB specification against input signal levels to prevent compression. Confirm compatibility with standard 50 Ω system impedance and SMA interface requirements.

Part Context

This model belongs to the LNA series by L3 Narda-MITEQ, now part of L3Harris. The series is characterized by robust performance in harsh environments, often featuring hermetic sealing options. These amplifiers are engineered for reliability in aerospace, defense, and commercial satellite communications, offering consistent performance across defined temperature ranges.

Replacement Considerations

Direct substitutes may include other L3 Narda-MITEQ models within the same series that match the 100 MHz to 8 GHz frequency range and 40 dB gain requirement. Verify equivalent noise figures and P1dB ratings before substitution. Alternative manufacturers should be evaluated based on identical interface standards and power supply constraints.
