NT1021 is a single-chip dual-channel RF front-end consuming a very low power (47mW typical at 2.1V) and performing a simultaneous reception of both GPS/Galileo/BeiDou/GLONASS signals.
Highly configurable, RFIC can deliver different clock frequencies and provide either analog or digital output using onboard ADC circuits. This, alongside with configurable output CMOS level, makes the circuit compatible with many available baseband ICs.
Integrated stabilized voltage sources for TCXO, external LNA and active antenna alongside with integrated IF and PLL filters make the device easy to use with minimum external components. RFIC can be delivered in three variants: 6x6mm QFN40 or 5x5mm QFN32 packages, or unpackaged, in dies for SiP implementation.
IC is fabricated on SMIC CMOS 0.18 um technology.
