SKY55950-11

RF Front End (LNA + PA) Overview

The SKY55950-11 is a low-current GNSS LNA front-end module optimized for the 1.559 GHz to 1.606 GHz frequency range, supporting GPS, GLONASS, and Galileo systems. It integrates a low-noise amplifier with pre-filter and post-filter capabilities. Key electrical parameters include a small signal gain of 16 dB, a noise figure of 1.9 dB, and a P1dB compression point of 8 dBm. The device operates on a supply voltage ranging from 1.5 V to 3.6 V and consumes approximately 1 mA of current. It is housed in a compact 10-MCM (2.5x2.5 mm) package.
