MGA-87563 is an economical, easy-to-use GaAs MMIC amplifier that offers low noise and excellent gain for applications from 0.5 to 4 GHz. It is packaged in an ultra-miniature SOT-363 package, requires half the board space of a SOT-143 package, and is only 4.5 mA.
The MGA‑87563 is a GaAs MMIC low‑noise amplifier designed for 0.5‑4 GHz applications such as PCS, ISM, cellular and GPS. It offers a minimum noise figure of 1.6 dB and a typical gain of 12.5 dB at 2.4 GHz, while drawing only 4.5 mA from a single +3 V or +5 V supply.
The datasheet provides absolute maximum ratings, detailed electrical specifications, typical performance curves, recommended PCB layouts, and ordering information. It also includes application notes on biasing, input and output matching, and stability enhancements for low‑frequency operation.
