Datasheet

OVERVIEW

NT1062 is a 2-channel RF Front-End ICintended for the reception of GNSS (GPS, GLONASS, Galileo, BeiDou, NavIC, GAGAN, QZSS) signals like L1, L2, L3, L5, E1, E5a, E5b, E6, B1, B2, B3 and also satellite-based augmentation systems like OmniSTAR and SBAS in various combinations. It makes possible to benefit from all the advantages of acquiring multiple system with single chip. Two real channels with image rejection are designed with single conversion low-IF architecture. External active antenna can be connected to RF input that is common for two channels. As an option two separate RF inputs can be used for operating with external passive antennas. Each channel setting, including output signal frequency bandwidth, AGC options, mirror channel suppression option, etc., can be set for each channel individually. NT1062 includes two fully independent frequency synthesizers that have the common reference (TCXO) input making LO signals coherent in terms of frequency.
