LNA-20-08001800-23-15P

Overview

The LNA-20-08001800-23-15P is a low-noise amplifier from the L3 Narda-MITEQ series, designed for RF signal conditioning. It operates within an 8 GHz to 18 GHz frequency range, providing a minimum gain of 20 dB and a noise figure of 2.3 dB. The device delivers a P1dB output power of +15 dBm with a supply voltage of +15 VDC and typical operating current of 225 mA. Input and output impedances are 50 Ω with a VSWR of 2:1. It functions in temperatures from -55 °C to +85 °C and uses SMA connectors in a module package.

Feature Summary

• Provides stable amplification across the 8–18 GHz band with low noise characteristics
• Features internal voltage regulation for consistent power management
• Ensures unconditional stability under various load conditions
• Includes standard 50 Ω impedance matching for easy system integration

Applications

• VSAT satellite communication ground station receivers
• GPS, GLONASS, and BeiDou navigation receiver front-ends
• Radar receiver echo signal pre-amplification
• Deep space exploration weak signal reception

Procurement Notes

Verify the specific part number suffix against official L3Harris or Amphenol Narda-MITEQ documentation to confirm exact performance parameters. Ensure compatibility with existing SMA connector interfaces and +15 VDC power requirements. Confirm RoHS compliance status if required by project specifications. Check for any recent product lifecycle updates or obsolescence notices directly from the manufacturer before finalizing procurement orders.

Selection Notes

Select this component when a low noise figure of 2.3 dB is critical for sensitivity in the 8–18 GHz range. It is suitable for applications requiring high linearity with +15 dBm P1dB output. Consider its module form factor and SMA connectivity for direct board integration. Evaluate thermal management needs given the -55 °C to +85 °C operating range and 225 mA current draw for robust environmental deployment.

Part Context

This model belongs to the LNA series of low-noise amplifiers manufactured by L3 Narda-MITEQ, now part of L3Harris Technologies. These amplifiers are engineered for high reliability in demanding RF environments. The series typically features ruggedized construction and stable performance across wide temperature ranges, serving as key components in satellite communications and defense electronics systems.

Replacement Considerations

LNA-20-08001800-32-20P offers similar frequency coverage but differs in gain (30 dB) and noise figure (3.2 dB). Verify that the higher gain and slightly increased noise figure meet system requirements. Ensure mechanical and electrical interface compatibility remains unchanged during substitution.
