T7B04

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

  • A.Poor amplifier noise figure
  • B.Poor amplifier linearity
  • C.Low SWR
  • D.High SWR (correct answer)

WhyHigh SWR might be the cause of low RF power output from a solid-state transceiver. A high SWR reflects power back toward the transmitter instead of letting it reach the antenna, and most solid-state transceivers automatically reduce their output power to protect the final amplifier transistors when that happens, answer D. Poor noise figure (A) and poor linearity (B) are receiver- and distortion-related issues rather than causes of reduced output, and low SWR (C) is the opposite of a fault condition, a low SWR is what you want.
