SY1007A
GNSS RF Front-End
Description
The SY1007A is a radiation hardened L-band RF downconverter for GNSS receivers aimed at the professional and space markets. It is an improved version of the legacy SY1007 device that offers a LO phase noise improvement of about 10dB below 100Hz offset, a lower noise gain control input and SEL-free operation up to a LET = 85MeV·cm2/mg.
This device is designed in a 0.35μm SiGe process. Like its predecessor, the SY1007A is a programmable dual conversion super-heterodyne receiver that includes all functional blocks needed to implement the complete RF front-end of multiband GNSS receivers. It can be configured to receive most GPS, Galileo, GLONASS and BeiDou signals in the L-band up to a bandwidth of 24MHz. Since it is pin-to-pin compatible with the SY1007, the SY1007A can be used to upgrade existing systems designed around the SY1007.Only an adjustment of a few components will be required.

IMPORTANT WARNING! Users of the previous SY1007 chip are kindly requested to download and read with attention the following Application Brief AB-01, in which few additional precautions needed to adapt the old SY1017C design to the use of the new chip SY1017A are outlined.
The reference plane for the S-parameters is at the device's balls. PCB strays are not included and shall be added manually to the simulation, otherwise the results will most likely be invalid.
