Overview
AN18401A, using SiGe process, realizes on-chip LNA with low noise figure and ultra low-power current consumption. As not only the LNA but also VCO is completely built in the IC, it enables further miniaturization of GPS modules and a reduction of components.

Features
● A single chip IC for the LNA block with low noise figure (NF = 1.6 dB)
● Low current consumption: 24 mA
● Achievement of saving the space of sets according to significant reduction of external parts (LNA, BPF, VCO, etc)

Applications
● For portable terminal, car navigation system
