Datasheet of NT1069




NT1069-1 is an interference resistant RF Front-End IC which is intended for reception of all existing Global Navigational Satellite Systems (GNSS) signals such as GPS, GLONASS, Galileo, BeiDou, NavIC, QZSS in L1, L2, L3, L5, E1, E5a, E5b, E6, B1, B2, B3, S bands. The distinctive feature of NT1069-1 is high noise immunity, which is achieved by high linearity of the channel. The receiving channel consists of LNA, highly linear mixer, 2-stage IFA and output linear buffer. Gain of LNA and IFA can be controlled externally. Two-stage RF frequency filtration is performed on external components with the aim of noise immunity improvement. For better filtration all external components should be specially selected for each GNSS.
