Description

A magic hybrid tree, more commonly known as a magic tee, is a four-port waveguide component that combines the properties of both E-plane and H-plane tees. It's widely used in microwave systems for signal splitting, combining, and phase manipulation. 🔹 Structure & Ports: - Port 1 & 2: Collinear arms (input/output) - Port 3: H-plane port (sum port, Σ) - Port 4: E-plane port (difference port, Δ) 🔹 Key Operating Principles: - A signal fed into Port 3 (H-plane) splits equally into Ports 1 and 2 in phase. - A signal fed into Port 4 (E-plane) splits equally into Ports 1 and 2 180° out of phase. - Signals fed into Ports 1 and 2 combine at Port 3 (sum) and cancel at Port 4 (difference), or vice versa. 🔹 Applications: - Balanced mixers - Duplexers - Phase shifters - Radar systems (to isolate transmitter and receiver paths)
