Description

NT1066 is a 4-channel RF Front-End IC (3 wideband IQ and 1 narrowband IQ) that covers simultaneously all GNSS (GLONASS, GPS, Galileo, BeiDou, QZSS, NavIC) signals at all frequency bands. It makes possible to benefit from all the advantages of acquiring multiple system simultaneously. Channels “A”, “B” and “C” are designed with single conversion low-IF architecture, individually programmable and intended to receive L1, E1, B1, E6, B3, L2, L3, B2, L5, E5 in various combinations. IQ and image suppression modes are available, other options can be discovered in feature list. Channel “D” is dedicated to operate in S band or L2, L3, L5 bands of GNSS and has zero-IF architecture. S and L5 bands combining lets user to eliminate effectively ionospheric distortion utilizing large signal base. As alternative, channel “D” can be ‘on a fly’ software-reconfigured to receive real-time corrections data transmitted over FM, VHF and UHF bands.

NT1066 does also integrate 4 fractional-N synthesizers that have the common reference frequency input. Wide list of attractive features and high level of customization make NT1066 capable to meet a demand of researchers and OEM developers in special applications: high precision positioning, goniometric, driverless car systems, professional drones and related areas.
