PGA-103+ - Low Noise MMIC Amplifier SOT-89 (Mini-Circuits)

Product Description

The PGA-103+ Mini-Circuits is a low noise MMIC amplifier (LNA) in a SOT-89 package, designed for RF applications from 0.05 to 4 GHz. With its high gain and very low noise figure, the PGA-103+ is ideal as a first RF amplification stage in sensitive receivers, SDR systems, and high-performance RF front-ends.

Main Features

• Frequency range: approx. 0.05–4 GHz
• Type: Low Noise Amplifier (LNA) MMIC
• Package: SOT-89, easy to integrate on compact PCBs
• High gain: ideal for initial RF amplification stages
• Single-supply operation for simplified design
• High linearity and stability for professional RF systems

Typical Applications

The Mini-Circuits PGA-103+ is used in a wide range of RF and microwave applications requiring a very low noise amplifier:

• SDR (Software Defined Radio) receivers and RF scanners
• Low noise RF front-ends for broadband systems
• Wireless and microwave communication systems
• Radar systems and RF sensing applications
• Experimental RF projects and broadband prototypes

Advantages of the PGA-103+ in RF Design

Compared to other low noise RF amplifiers, the PGA-103+ Mini-Circuits offers an excellent balance of gain, noise figure, linearity, and ease of integration. The SOT-89 package ensures good thermal performance and compact PCB layout, while MMIC technology provides repeatability and stability over time.

It is a great choice for those needing a reliable wideband LNA 0.05–4 GHz with professional-grade performance, available at a competitive price with stock ready to ship.
