Abstract
One embodiment of the present invention provides an RF front-end system. The RF front-end system includes one or more RF front-end components and a programmable logic device, which has a baseband interface for coupling to a baseband digital signal processor (DSP), and a set of component interfaces for coupling to the one ore more RF front-end components. The programmable logic device is configured to: receive, from the baseband DSP via the baseband interface, a command which includes an address and a control signal; identify a component interface from the set of component interfaces based on the address; and send the control signal to the identified component interface, thereby enabling the baseband DSP to control a front-end component coupled to the programmable logic device via the identified component interface.
