Q. Coupler that is mostly used in balanced amplifiers to achieve the required performance is:

  • (A) branch line coupler
  • (B) wilkinson coupler
  • (C) lange coupler
  • (D) waveguide coupler
💬 Discuss
✅ Correct Answer: (C) lange coupler
Explanation: lange couplers are broadband couplers and are compact in size. since the bandwidth of a balanced amplifiers depends on the bandwidth of the coupler used. lange coupler is thus preferred over couplers.
