سؤال 274

Which of the following might be the cause of low RF power output from a solid-state transceiver?

  1. Poor amplifier noise figure
  2. Poor amplifier linearity
  3. Low SWR
  4. High SWRپاسخ درست

توضیح

High SWR means much of the forward power is reflected back to the transmitter, and modern solid-state radios sense this and automatically fold back output power to protect the finals, so indicated output drops. Low SWR is the desired condition and does not reduce output.
