Patent ID: 7720506

Claim:
A method of providing a structure for software defined radio (SDR), the method comprising: providing a set of antennas; coupling an antenna switch circuit to the set of antennas, the antenna switch circuit comprising a plurality of terminals, each of the terminals being coupled to a respective antenna of the antennas and a respective RF bank of a plurality of RF banks, the respective RF bank being associated with the respective antenna, each of the RF banks including an input filter, an output filter, a low noise amplifier and a power amplifier, each of the antennas being associated with at least one of a specific radio application; coupling a set of RF front ends to the antenna switch circuit, the RF front ends functioning as banded frequency converters, the RF front ends being configurable for each of the radio applications, wherein an antenna switch in the antenna switch circuit is capable of coupling any of the RF front ends to any of the RF banks; and connecting via the antenna switch circuit one of the RF banks associated with one of the antennas to one of the RF front ends configured for one of the radio applications, the one of the radio applications being associated with the one of the antennas.
