POWER CONTROL OF A POWER AMPLIFIER USING PULSE WIDTH MODULATION OF INPUT SIGNAL |
摘要 |
A transmitter comprises a pulse shaper that replaces a portion of a pulse in a basic signal (RFP) by a neutral value (0). Accordingly, the pulse shaper provides a pulse- shaped signal (RFS) that comprises a thinned version of the pulse and, adjacent thereto, the neutral value. An output amplifier, which amplifies the pulse-shaped signal, is in a quiescent state when the pulse-shaped signal has the neutral value. |
