STMicroelectronics STA5635A
The STA5635A is a fully integrated GNSS RF front-end able to support different bands (L1, L2, L5, L6 and L) thanks to a programmable and flexible RF-IF chain driven by a fractional PLL. The RF_IF chain is followed by a 2-bit ADC able to convert the IF signal to sign (SIGN) and magnitude (MAG) bits. The MAG bit is internally used to control the variable gain amplifiers.| Part No. | STA5635A |

DESCRIPTION
In particular, G5RF is able to manage all the GNSS constellations available and planned in the next future like GPS, Galileo, Glonass, BeiDou, IRNSS and QZSS. The VGA gain can also be set via the SPI interface. Additionally, the STA5635A is able to manage the L-band signal from 1525 to 1559 MHz, through a dedicated 10 bit ADC.
