THE DUAL ANTENNA DIVERSITY TRANSMITTER AND SYSTEM WITH IMPROVED POWER AMPLIFIER EFFICIENCY |
摘要 |
Provided is a dual antenna diversity transmitter and system having improved power amplifier efficiency, and further comprising switches in the dual antenna diversity transmitter and system, to minimize a DC input power consumed by the power amplifier depending on the required transmitting output power and operate efficiently the power amplifier, whereby signal linearity can be maintained and the power amplifier can be efficiently operated in a more simplified manner, as compared to the conventional high efficiency power amplifier. |
