Voltage standing wave ratio detector for power amplifier

摘要

A voltage standing wave ratio (VSWR) detector (1600) is provided. The voltage standing wave ratio (VSWR) detector (1600) includes a power amplifier over-voltage indication circuit generating an output (1602);
a power amplifier over-current indication circuit generating an output (1604), a decision circuit receiving the power amplifier over-voltage indication circuit output (1602) and the power amplifier over-current indication circuit output (1604) and generating an output based on the power amplifier over-voltage indication circuit output (1602) and the power amplifier over-current indication circuit output (1604), and
one or more power control actuation circuits (1206) receiving the decision circuit output and adjusting a power level of a power amplifier (1202).
