Extra exam question E6E07
Subelement E6, CIRCUIT COMPONENTS· Group E6E
What type of transmission line is often used for connections to MMICs?
- A.Miniature coax
- B.Circular waveguide
- C.Parallel wire
- D.Microstrip (correct answer)
WhyMicrostrip is the transmission line type often used for connections to MMICs. Microstrip, a conductive trace running over a ground plane on a circuit board, is the transmission line type commonly used to connect to MMICs, since it's easy to fabricate directly into the same PCB the MMIC is mounted on and can be designed for a controlled characteristic impedance, answer D. Miniature coax, circular waveguide, and parallel-wire line are all real transmission line types but aren't the typical choice for direct MMIC board-level connections.
