Extra exam question E5D04
Subelement E5, ELECTRICAL PRINCIPLES· Group E5D
Why are short connections used at microwave frequencies?
- A.To increase neutralizing resistance
- B.To reduce phase shift along the connection (correct answer)
- C.To increase compensating capacitance
- D.To reduce noise figure
WhyShort connections are used at microwave frequencies to reduce phase shift along the connection. Short connections are used at microwave frequencies to reduce the phase shift a signal accumulates traveling along that connection, since even a short physical length becomes a significant fraction of a wavelength at microwave frequencies, and excess phase shift can seriously degrade circuit performance, answer B. It isn't about neutralizing resistance, adding compensating capacitance, or reducing noise figure, those aren't what short microwave interconnects are primarily for.
