A power interface circuit (64) is provided that uses an n-channel MOSFET (66) to control the switching of a power supply (46) to a TDMA power amplifier (58). When turned on, the n-channel MOSFET (66) connects the power supply (46) to the power amplifier (58), and when turned off, it disconnects the power supply from the power amplifier. The power interface circuit (64) includes a switch control circuit (70) that controls the switching state of the n-channel MOSFET (66) in response to a switch control signal. The switch control signal has a first binary state during which the n-channel MOSFET (66) is turned off and a second binary state during which the n-channel MOSFET is turned on.
