Patent ID: 8340622

Claim:
A master radiofrequency integrated circuit, comprising: a radiofrequency side contact connectable to an antenna, for receiving radiofrequency signals, via said antenna, from a wireless communications network; a master radiofrequency module connected to said radiofrequency side contact, for converting said radiofrequency signals into baseband signals; and a RF to baseband interface side contact connected to the master radiofrequency module and connectable to a RF to baseband interface side contact of a baseband integrated circuit, for transmitting said baseband signals from the master radiofrequency module to said baseband integrated circuit; wherein said master radiofrequency module includes: a slave control unit for selecting an enabled module which is allowed to transmit data to the baseband integrated circuit from the master radiofrequency module and a slave radiofrequency module on another radiofrequency integrated circuit; and a slave side contact connected to said slave control unit and connectable to said slave radiofrequency module, for transferring information indicating when a baseband side contact of said slave radiofrequency module is connected to said contact of said baseband integrated circuit, enabling a transmission of baseband signals to said baseband integrated circuit by said slave radiofrequency module when said slave radiofrequency module is said enable module and inhibiting said transmission when said slave radiofrequency module is a non-enabled module.
