Microwave Communication
44.
A matched generator (Zg = Z0) with 1 Ω available. If all ports are matched, the power delivered at ports 1, 2, 3 respectively are
0.5 W, 0.5 W, 0 W
0 W, 0 W, 1 W
0.33 W each
0 W, 0.25 W, 0.25 W
Answer: Option
Explanation:

Since all ports matched, input SWR = 1. No power is reflected and Pin = P4 = 1 W.

This power splits between ports 1 and 2. Therefore P1 = P2 = 0.5 Ω, P3 = 0.
