Qualcomm WTR5975 Gigabit LTE Transceiver

Qualcomm WTR5975 Gigabit LTE Transceiver

The WTR5975 is a member of the Snapdragon 835 family found in the Samsung Galaxy S8 and is the world’s first single-chip RF IC supporting Gigabit Class LTE, LTE-U, and LAA with 5 GHz unlicensed band support. The highly integrated WTR5975 supports up to 4x downlink CA, 2x uplink CA, all 3GPP-approved bands, including 3.5 GHz bands 42 and 43, and 4x4 MIMO in a single transceiver chip, dramatically reducing the footprint required to support advanced CA and MIMO configurations
