Patent ID: 8903409

Claim:
An arrangement for a receiver which is adapted to allow carrier aggregation in a wireless communication system, comprising a plurality of radio frequency (RF) blocks, each of which is inherently adapted to operate substantially across one of the following particular groups of frequency ranges, in MHz, of: A) 698-960; B) 1428-1660; C) 1710-2200; D) 2300-2690; E) 3400-3800; the arrangement being adapted to operate in a multiple antennas and/or a multiple input/multiple output (MIMO) system, wherein, for each channel/antenna, there are provided two RF amplifiers adapted for group A, one RF amplifier adapted for group C and one RF amplifier adapted for group D, the arrangement further adapted to operate over two channels of a MIMO system, and having an input and/or output to the respective antenna of each channel; wherein for each channel there is a first multiplexer to multiplex the output from one of the RF amplifiers adapted for group A, with the output from the RF amplifier adapted for group C, and a second multiplexer to multiplex the output from the other group A adapted amplifier with the output from the group C adapted amplifier and the output from the group D adapted amplifier.
