LNA-40-00100400-30-20P

Overview

The LNA-40-00100400-30-20P is a low-noise amplifier manufactured by L3 Narda-MITEQ, designed for the 100 MHz to 4 GHz frequency range. It provides a minimum gain of 40 dB with a noise figure of 3.0 dB and a P1dB output power of +20 dBm. The device operates on a +15 VDC supply with a typical current draw of 350 mA. Input and output impedance are 50 Ω, with a VSWR of 2:1. It functions within an operating temperature range of -55 °C to +85 °C and is housed in a module package with SMA connectors.

Feature Summary

• High gain performance suitable for sensitive signal reception
• Low noise figure for improved system sensitivity
• Standard 50 Ω input/output matching for easy integration
• Robust construction for reliable operation in demanding environments

Applications

• VSAT satellite communication systems
• RF microwave link receivers
• Wireless communication equipment front-ends
• Test and measurement instrumentation

Procurement Notes

Verify the specific part number suffix against official L3Harris or Amphenol Narda-MITEQ documentation to confirm exact electrical tolerances and connector types. Ensure compatibility with existing system voltage requirements (+15 VDC) and thermal management solutions given the 350 mA current consumption. Confirm that the SMA connector interface matches the board layout and cable assemblies used in the design.

Selection Notes

Select this component when high gain (40 dB) and low noise (3.0 dB) are required across the L-band and lower S-band frequencies. Consider the +20 dBm output power capability for driving subsequent stages without significant distortion. Evaluate the module form factor and SMA connectors for space constraints and interconnection needs. Verify that the operating temperature range meets the environmental conditions of the intended deployment site.

Part Context

This model belongs to the LNA series from L3 Narda-MITEQ, now part of L3Harris Technologies. The series is known for providing stable, high-performance amplification for RF and microwave applications. The naming convention typically indicates gain, frequency range, noise figure, and output power specifications, allowing engineers to quickly identify suitable components for signal chain optimization.

Replacement Considerations

Consult official L3Harris or Amphenol Narda-MITEQ cross-reference guides for verified substitutes. Generic replacements may not match the specific 40 dB gain or 3.0 dB noise figure requirements. Ensure any alternative maintains the 100 MHz to 4 GHz bandwidth and +15 VDC operating voltage.
