Abstract:
1. An integrated circuit comprising: a digital interface for connection to a host controller; an antenna connection for connection to an antenna; a radio frequency transceiver for communicating data in accordance with a first radio communication protocol, the radio frequency transceiver being configured to communicate radio frequency signals over the antenna connection in response to data exchanged over the digital interface; and radio loop-through circuitry configured to exchange radio frequency signals according to a second radio communication protocol with another collocated integrated circuit, the radio loop-through circuitry being configured to provide radio frequency signals according to the second radio communication protocol received at the antenna connection to an output connection of the integrated circuit, wherein the first radio communication protocol is different from the second radio communication protocol; wherein the radio loop-through circuitry is further configured to provide radio frequency transmit signals received at an input connection of the integrated circuit from the said another integrated circuit, to the antenna connection.
