The SY1007 is a radiation hardened L-band RF downconverter for GNSS receivers aimed at the professional and space markets. Listed in the ESA preferred part list (EPPL), Part-2. This device is designed in a 0.35µm SiGe process and includes all functional blocks needed to implement the complete RF front-end of multiband GNSS receivers, thus allowing a substantial reduction of BOM, size and weight with respect to discrete designs. It directly interfaces to the ESA AGGA-4 GNSS base-band processor.

The SY1007 is a programmable dual conversion superheterodyne receiver. Both the RF and the IF local oscillators can be independently programmed to accommodate various frequency plans. It can be configured to receive all GPS, all GLONASS and most Galileo signals in the L-band up to a bandwidth of 24MHz by selecting the appropriate external components and configuring the RF and IF PLLs. The output is analog quadrature (I/Q) at base-band. Four low latency power down modes are provided to aid in implementing different power saving schemes. Since the SY1007 mainly targets the space market, a variant qualified to ESA ESCC9000 for satellite applications is available. This variant has demonstrated latch-up and radiation damage free operation. The SY1007 comes into a compact 6mm x 6mm ceramic-metal hermetic BGA package containing no organic materials.
