摘要

"Interface circuit to output to a power amplifier, transmitter of time division multiple access, and,Process for selectively providing a supply voltage to a power amplifier ".An interface circuit of power (64) is presented which uses a MOSFET Channel - n (66) to control the switching of a power source (46) to a power amplifier TDMA (58).When activated, the MOSFET Channel - n (66) connects the power supply (46) to the power amplifier (58), and, when deactivated, disconnects the power source of the power amplifier.The interface circuit of power (64) includes a switching control circuit (70) that controls the switching condition of the MOSFET Channel - n (66) in response to a control signal of switching.The control signal switch has a first binary state during which the MOSFET Channel - n (66) is disabled and a second state torque during the quaal the MOSFET Channel - n is activated.
