Abstract
According to embodiments of the present disclosure, circuitry () and method () are provided for controlling a power amplifier () in a transmit/receive switching system. The circuitry () comprises a load circuit () for at least partly reducing a magnitude of a swing of a power supply voltage caused by a variation in load of the transmit/receive switching system that occurs upon initiation of a transmission by the transmit/receive switching system. The circuitry () further comprises a first switch (), coupled in series with the load circuit (), operable to switch on to couple the power supply voltage to a ground voltage via the load circuit (). The circuitry () further comprises a control circuit () configured to switch on the first switch () at a first timing, and to switch off the first switch () and turn on the power amplifier () at a second timing. The first timing is a time interval ahead of the second timing.
