LNA-20-01000200-25-20P

Overview

The LNA-20-01000200-25-20P is a low-noise amplifier manufactured by L3 Narda-MITEQ, designed for VSAT applications. It operates within a frequency range of 1 GHz to 2 GHz. The device provides a gain of 25 dB and achieves a noise figure of 1.0 dB. It delivers a P1dB output power of +20 dBm. The unit requires a supply voltage of +15 VDC with a typical operating current of 225 mA. Input and output impedance are matched to 50 Ω, with a maximum VSWR of 2:1. The component is housed in a module package equipped with SMA connectors.

Feature Summary

• Unconditional stability across various load conditions
• Standard 50 Ω input/output port matching for easy system integration
• Built-in DC voltage regulation for stable power management

Applications

• VSAT satellite communication ground station receiver front ends
• Satellite navigation receiver front ends (GPS, GLONASS)
• RF and microwave link signal amplification
• Test and measurement instrumentation

Procurement Notes

Verify the manufacturer part number against official L3 Narda-MITEQ documentation to ensure authenticity. Confirm that the specific suffix matches the required electrical parameters, particularly the 25 dB gain variant. Check RoHS compliance status and environmental ratings if deployment in harsh conditions is planned. Request datasheets directly from authorized distributors or the manufacturer to validate performance curves and pinout configurations before finalizing procurement orders.

Selection Notes

Select this component when a 1 GHz to 2 GHz frequency range is required with high linearity and low noise characteristics. The 25 dB gain specification distinguishes it from other variants in the LNA-20 series. Ensure the system can accommodate the +15 VDC supply requirement and 225 mA current draw. Verify that SMA connector interfaces align with existing board layouts and cable assemblies. Consider thermal management requirements based on the specified operating temperature range.

Part Context

This model belongs to the LNA-20 series of low-noise amplifiers produced by L3 Narda-MITEQ. The series is characterized by rugged construction and consistent performance for satellite communications. Variants within the series differ primarily in gain, frequency range, and noise figure specifications while maintaining similar physical packaging and power requirements.

Replacement Considerations

LNA-20-01000200-10-15P offers similar frequency coverage but with lower gain (+15 dB) and different power handling. LNA-20-02000400-25-20P covers a higher frequency band (2 GHz to 4 GHz). Direct substitution requires verifying gain, noise figure, and power supply compatibility.
