Outline (PRODUCT DESCRIPTION) SG803 is our company development of the dual-channel RF chip which receive four frequency signal of GPS L1 / BD B1 + BD B2 / B3 and it bases on a CMOS process. What’s more, it supports dual-channel working independently and simultaneously. Inhibiting structure mirroring, on-chip integrated filter with ESD protection, and this chip has good linearity and anti-jamming capability. This transceiver chip uses 40-pin QFN package which measure is 5 × 5 mm2.
