PGA-103+
Overview
The PGA-103+ is a high-dynamic-range, monolithic E-pHEMT amplifier designed for applications operating between 50MHz and 4GHz. It provides a flat gain profile of approximately 18dB and a low noise figure of 1.5dB, making it an excellent choice for receiver front-ends and driver stages. The device operates from a single 3V or 5V supply and is housed in a standard SOT-89 package for efficient thermal management.
Why Choose This Part
This amplifier offers a high P1dB of 23.2dBm, ensuring excellent linearity and resistance to compression in high-signal environments. Its wide frequency range from 50MHz to 4GHz allows for platform standardization across multiple RF protocols. The E-pHEMT technology provides a very low noise figure of 1.5dB at 4GHz, which is critical for maintaining high signal-to-noise ratios in weak-signal applications.
Applications
Key Specifications
Getting Started
When integrating the PGA-103+, ensure proper thermal grounding of the SOT-89 package's center lead to manage the 97mA operating current. Use high-frequency layout techniques including 50-ohm microstrip lines and proper decoupling of the VDD supply line as close to the device as possible. Designers should consult the official Mini-Circuits characterization curves for precise matching network values at specific target frequencies between 50MHz and 4GHz.
