Abstract
An antenna switch module includes a radio-frequency input port, a radio-frequency output port, a radio-frequency core connected between the radio-frequency input port and the radio-frequency output port, the radio-frequency core being configured to operate in each of a plurality of operational states, the plurality of operational states including a first subset of operational states and a second subset of operational states, and a decoder configured to receive an input signal indicating a first operational state of the radio-frequency core, the first operational state being of the first subset of operational states, generate an output control signal corresponding to the first operational state, detect a transition of the radio-frequency core to a second operational state, determine that the second operational state is of the second subset of operational states, and insert an intermediate output signal corresponding to an intermediate operational state of the radio-frequency core in response to said determination.
