Low Noise Amplifier, 9KHz~20GHz, Gain 18dB, NF 2.5dB, P1dB 11dBm

This product is a super wideband low-noise amplifier covering a frequency range from 9kHz to 20GHz, specifically designed for high-performance receiver front ends to meet the comprehensive requirements of broadband, low noise, and high linearity in multi-band, multi-standard communication systems. The following briefly introduces its features and applications:

Features:

1. Ultra-wideband coverage: The operating frequency range spans from 9kHz to 20GHz, enabling full-band signal amplification from low frequencies to microwave bands with a single device. This design significantly simplifies the complexity of multi-channel reception architectures, providing high-integration solutions for broadband communication, electronic reconnaissance, and instrumentation applications.
2. High gain and flatness: Provides a stable 18dB gain across the entire operating frequency band, effectively enhancing the signal strength of the receiving link, compensating for subsequent link losses, and ensuring weak signals are not overwhelmed.
3. Low noise figure: The noise figure across the full frequency band is 2.5dB. This feature minimizes the additional noise introduced by the amplifier itself, effectively preserving the signal-to-noise ratio of weak signals and significantly enhancing the receiver system's capability to detect and capture weak signals.
4. High linearity: While delivering high gain and low noise, its output 1dB compression point reaches +11dBm, ensuring the amplifier resists distortion when handling strong interference signals or adjacent channel signals, thereby safeguarding the dynamic range and communication quality of the receiving system.

Applications:

1. Military and aerospace: Used for radar warning, electronic countermeasures (ESM), satellite communication (SATCOM) ground stations and other systems to enhance the interception and listening capabilities of weak signals.
2. Testing and measurement: As a preamplifier for high-end testing equipment such as spectrum analyzers and network analyzers, it can expand its measurement dynamic range and testing lower limit.
3. Base station and wireless communication: Improve the uplink performance of cellular base stations and private network communication (such as emergency communication), expand coverage, and enhance the call quality for edge users.
4. Research and astronomy: Applied to radio telescopes to help scientists explore extremely weak electromagnetic wave signals from deep within the universe.
