GT4899B
The GT4899 is a QPDT switch with one common control inputs targeted at dual SIM card multiplexing. It is optimized for switching the WLAN-SIM data and control signals and dedicates one channel as a supply-source switch. The switches are fully bi-directional, allowing both multiplexing and de-multiplexing operation. Break-beforemake operation is guaranteed. The device operates from a +1.65V to +5.5V supply and over the extended -40°C to +85°C temperature range. It is available in QFN-3×3-16L and UTQFN1.8×2.6-16L.
