Low Noise Amplifier, 0.002~1.2GHz, Gain 30dB, NF 1.0dB, P1dB 15dBm

Qualwave Inc. has launched a low-noise amplifier with the model number QLA-2-1200-30-10. This product delivers exceptional performance across an ultra-wide frequency range of 0.002GHz to 1.2GHz, providing solutions for fields such as communications, testing and measurement, and aerospace. The following briefly introduces its characteristics and applications:

Characteristics:

1. Ultra-wideband coverage (2MHz-1200MHz): A single device can cover the majority of frequency bands from HF, VHF to L-band, significantly simplifying the design complexity of multi-band, multi-standard reception systems.
2. High gain and flatness (30dB): Provides a stable gain of up to 30dB throughout the entire operating frequency band, effectively improving the signal strength of the receiving link, compensating for subsequent link losses, and ensuring that weak signals are not overwhelmed.
3. Extremely low noise figure (1.0dB): This is the core competitiveness of this product. A noise figure of 1.0dB means that the amplifier itself introduces extremely low noise, which can preserve the signal-to-noise ratio of the original signal to the greatest extent possible, thereby significantly improving the sensitivity of the receiver and enabling it to capture weak signals that were previously difficult to detect.
4. High linearity (P1dB+15dBm): While providing high gain and low noise, its output 1dB compression point can reach up to+15dBm, ensuring that the amplifier is not easily distorted when processing strong interference signals or large signals in adjacent channels, guaranteeing 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.
