The HS1109P is a Low Noise Amplifier (LNA) for GPS/Beidou/GLONASS/Galileo/Compass applications. It can deliver 17dB power Gain and an excellent noise figure (NF) of 0.55dB at only 2.9mA current consumption. The output matching components are integrated inside the device. Only one external input matching inductor is required. A power down mode was controlled by the enable logic signal.

The HS1109P is manufactured in a compact, 6- pin 1.1 x 0.9 x 0.6 mm package. A functional block diagram is shown in Figure 1. The pin configuration and package are shown in Figure 2.
