Digital transmitter with high power output

An RF transmitter (1) has a gate segmented power output stage (2) and a digital driver (5). The gate segmented power output stage (2) includes a field effect transistor having a plurality of gate fingers (32) and drain fingers (31) defining a gate periphery. The field effect transistor comprises a plurality of power output stage segments (3), each power output stage segment corresponding to a respective portion of the gate periphery, and each power output stage segment having a respective power output stage segment input (4). The digital driver (5) has a control output (6) connected to a corresponding one of the respective power output stage segment inputs (4), and is configured for individually switching each of the power output stage segments (3) between a turn-on mode and a turn-off mode according to one or more input signals, to obtain a modulated RF carrier signal at the output (7) of the gate segmented power output stage (2). 一种RF发射器(1)，具有栅极分段的功率输出级(2)和数字驱动器(5)。栅极分段的功率输出级(2)包括场效应晶体管，场效应晶体管具有多个栅极指(32)和限定
