SGA-5386Z

RF Amplifiers Overview

The SGA-5386Z is a DC to 5000 MHz cascadable SiGe HBT MMIC amplifier manufactured by RFMD. It utilizes a Darlington configuration with 1 micron emitters to achieve high FT and excellent thermal stability. The device operates within a frequency range of 0 Hz to 5 GHz, providing a typical noise figure of 4 dB and a gain of approximately 14.9 dB. Packaged in a surface-mount SOT-86 outline, it is designed for integration into various RF front-end architectures requiring low-noise amplification.
