LTE-A/LTE/WCDMA RF Transceiver

AK1587 is a FDD-LTEA /TD-LTEA/FDD-LTE/TDD-LTE/WCDMA RF transceiver providing a highly integrated solution of 4Tx4Rx MIMO or two Carrier Aggregation (CA)channels in a single chip. Also included on chip are the associated built-in 2 blocks of Tx and Rx LO. A single AK1587 chip can support 2x2 MIMO configuration for inter-band CA, intra-band non-contiguous CA, intra-band contiguous CA, LTE/WCDMA dual mode, or 4x4 MIMO configuration for single Carrier Component (CC).
