RF Design Engineer Interview Questions and Answers

Optical fiber is a thin, flexible, transparent fiber made of glass or plastic that can transmit light signals over long distances.

• Optical fibers are used in telecommunications to transmit data over long distances.

• They are also used in medical equipment such as endoscopes and laser surgery tools.

• Optical fibers have a higher bandwidth than traditional copper wires, allowing for faster data transmission.

• They are immune to electromagnetic interference and can transmit signals ove...read more

S parameters are used to characterize linear electrical networks, while VSWR is a measure of how efficiently RF power is transmitted from a source to a load.

• S parameters are used in RF design to describe the behavior of linear electrical networks in terms of how they respond to signals at different frequencies.

• S parameters include S11, S12, S21, and S22, which represent the reflection and transmission coefficients between ports in a network.

• VSWR, or Voltage Standing Wave Rati...read more
