HIGH EFFICIENCY POWER AMPLIFIER ARCHITECTURE FOR OFF-PEAK TRAFFIC HOURS |
摘要 |
A power amplifier architecture (200) includes high and low power paths. The high power path may include a number of different amplifier structures. The low power path includes a switching element (270) configured to short a signal line to ground or provide an open between the signal line and ground. The low power path and an output of the high power path are summed at a summing junction (255). Circuitry is configured in a high power mode to turn on amplifier(s) in the amplifier structure, route an input signal (110) through a driver amplifier (115) to the high power path and place the switching element (270) in one position; the circuitry is configured in a low power mode to turn off the amplifier(s), route the input signal (110) through a driver amplifier (115) to the low power path and place the switching element (270) in the other position. |
