LNA-30-00100400-35-25P

Overview

The LNA-30-00100400-35-25P is a low noise amplifier module manufactured by L3 Narda-MITEQ. It operates within a frequency range of 100 MHz to 4 GHz. The device provides a nominal gain of 30 dB and maintains a noise figure of 35 dB, as indicated by the model designation. It is designed for VSAT applications and features a modular construction with SMA connectors. The unit requires a +15 VDC supply voltage and is built for robust signal conditioning in RF systems.

Feature Summary

• Provides stable amplification for weak RF signals in satellite communication links
• Features modular design with standard SMA connectors for easy integration
• Optimized for operation in VSAT ground station receiving frontends

Applications

• VSAT satellite communication system receiving chains
• RF signal conditioning modules
• Satellite navigation receiver frontends

Procurement Notes

Verify the specific datasheet version for the LNA-30-00100400-35-25P to confirm exact electrical parameters, particularly the noise figure value which appears inconsistent with typical L-band performance standards. Ensure compatibility with +15 VDC power supplies and 50 Ohm impedance matching requirements before integration into existing RF architectures.

Selection Notes

Select this component when a broadband low noise amplifier covering 100 MHz to 4 GHz is required for VSAT or general RF applications. Consider the modular form factor and SMA interface for prototyping or fixed installations where standard connectorization is preferred over waveguide or microstrip designs.

Part Context

This part belongs to the LNA series from L3 Narda-MITEQ, now part of L3Harris Technologies. The series includes various models tailored for different frequency bands and gain requirements. This specific model targets the lower microwave spectrum, serving as a critical component in receiving paths for satellite communications and radar systems.

Replacement Considerations

Consult official L3Harris/Narda-MITEQ documentation for direct cross-references. Alternative LNAs from manufacturers like Mini-Circuits or Qorvo may offer similar bandwidths but require verification of pinout, biasing, and mechanical dimensions.
