Overview
The SKY67153-396LF is a GaAs, pHEMT Low-Noise Amplifier (LNA) designed by Skyworks Solutions Inc. This device is characterized by its active bias, high linearity, superior gain, and industry-leading Noise Figure (NF) performance across a frequency range of 700 to 3800 MHz. It is fabricated using Skyworks' advanced pHEMT enhancement mode process and is packaged in a compact 2 x 2 mm, 8-pin Dual Flat No-Lead (DFN) package. The internal active bias circuitry ensures stable performance over temperature and process variations, and the device allows for external adjustment of the supply current.
