tryto plz help me solve this or guide me:?
A four port directional coupler is splitting 4:1 ratio and excessive loss (-10log (P3 + P2) / P1) equals 2.0 db.thecoupler directivity is 40 dB (1) What role will the input power to each port (2) calculate the loss to exploit their formula is-10log (P3/P2)
– I always hated physics, now I know why!
