What type of transmission line is often used for connections to MMICs?

  1. Miniature coax
  2. Circular waveguide
  3. Parallel wire
  4. Microstripپاسخ درست

توضیح

On the board carrying an MMIC the practical transmission line is microstrip, a track of controlled width running over a ground plane, which holds a defined impedance in very little space at microwave frequencies. Miniature coax, parallel wire, and circular waveguide are all impractical for connections of a few millimetres on a circuit board.
