AMPLICATION OF A RADIO FREQUENCY SIGNAL |
| 摘要 |
Apparatus (1) comprises envelope signal amplification circuitry (11) configured to receive an input envelope signal (ENV_in) indicative of an envelope of an input radio frequency signal (RF_in) and to output an amplified envelope signal (ENV_amp); and a radio frequency power amplifier (12) configured to receive a radio frequency control signal which is dependent on the input radio frequency signal(RF_in) and the input envelope signal (ENV_in), using the amplified envelope signal (ENV_amp) as its supply voltage, to output an amplified radio frequency signal (RF_amp). A method for amplification the radio frequency signal is also provided. |
