Features
AK1587 is a multi-band Femtocell/Smallcell LTE-A/LTE/WCDMA RF transceiver LSI with 2 Tx and 2
Rx LOs. Each LO has 2x2 MIMO capability, supporting up to total 40MHz BW inter- and intra- band
CA (Carrier Aggregation) configuration.
Application target are 2x2 MIMO FDD LTE-A / TD-LTE-A, 4x4 FDD LTE / TD-LTE, or 2x2 LTE +
WCDMA (dual mode).
