What is the function of magic tee?
A magic tee (or magic T or hybrid tee) is a hybrid or 3 dB coupler used in microwave systems. It is an alternative to the rat-race coupler. In contrast to the rat-race, the three-dimensional structure of the magic tee makes it less readily constructed in planar technologies such as microstrip or stripline.
Why is a hybrid tee called a magic tee?
The term “magic tee” is derived from the unusual manner in which the power gets divided/combined among various ports. A Magic Tee also known as Hybrid Tee can be used as a mixer with E arm port attached to input signal and H arm port attached to local oscillator and one port of collinear arms to matched load.
How many ports a magic tee network have?
A magic tee has four ports: Port 1 – Co-linear. Port 2 – Co-linear. Port 3 – Difference Port. Port 4 – Sum Port.
What is magic T junction?
A Magic Tee junction is formed by attaching two simple waveguides one parallel and the other series, to a rectangular waveguide which already has two ports. This is also called an E-H Plane Tee junction or Hybrid or 3dB coupler.
What is S matrix of magic tee?
Magic Tee or Hybrid Tee S Matrix Derivation It consists of four ports, if two waves of equal magnitude and same phase are fed into port 1 and port 2, the output will be subtractive and zero at port 3 and will be addictive at Port 4.
What is difference between magic tee and directional coupler?
Answer. A magic tee (or magic T or hybrid tee) is a hybrid or 3 dB coupler used in microwave systems. It is an alternative to the rat-race coupler. In contrast to the rat-race, the three-dimensional structure of the magic tee makes it less readily constructed in planar technologies such as microstrip or stripline.
What are the advantages of magic tee?
Benefits or advantages of Magic Tee ➨Output ports are decoupled to each other. As a result power delivered to one of the output ports does not depend on termination at other ports. ➨In magic tee output ports are perfectly matched.
What is T junction microwave?
In RF and microwave circuits, a waveguide or coaxial line junction with 3 ports is known as tee junction. This devices are mainly used for combining power and splitting power in a waveguide system.
What is H-plane tee?
An H-Plane Tee junction is formed by attaching a simple waveguide to a rectangular waveguide which already has two ports. The arms of rectangular waveguides make two ports called collinear ports i.e., Port1 and Port2, while the new one, Port3 is called as Side arm or H-arm. This H-plane Tee is also called as Shunt Tee.
How magic tee acts as a mixer?
E-Arm port is connected to the antenna and the H-Arm port is connected to the local oscillator. Port 2 has matched load which has no reflections and port 1 has the mixer circuit, which gets half of the signal power and half of the oscillator power to produce IF frequency.
What is a tee junction?
a road junction in which one road joins another at right angles but does not cross it.
What are the various types of tee in microwave?
There are two main types of Waveguide Tees:
- E-Plane Waveguide Tee. A waveguide tee is a 3 port device that is similar to a power divider.
- H-Plane Waveguide Tee.
What is difference between E-plane tee and H-plane tee?
The E-plane and H-plane are planes of reference for linearly polarized antennas, waveguides and other microwave devices. A waveguide which has three independent ports in a microwave circuit is known as a TEE junction. The output of E-plane Tee is 180 degrees out of phase and the output of H-plane Tee is in phase.
Which port is perfectly matched in magic tee?
Now we understand that ports 1 and 2 are perfectly matched to the junction. As this is a 4 port junction, whenever two ports are perfectly matched, the other two ports are also perfectly matched to the junction. The junction where all the four ports are perfectly matched is called as Magic Tee Junction.
What are the various type of tees?
What are the different types of t-shirts necklines?
- The Crew Neck style.
- The Henley – Y neck style.
- Polo t shirt collar styles.
- The Scoop Neck style.
- Raglan sleeve types.
- Sleeveless t shirt style.
- Cap sleeves t shirt style.
- Half, three quarter and full-length sleeve types.
What is E-plane H-plane magic tee?
An H-Plane TEE is a waveguide TEE in which the axis of its side arm is shunting the E field or parallel to the H field of the main guide and attaching the another waveguide.
What is microwave tee?
In microwave circuits, a wave guide with three independent ports is known as a ‘Tee’ junction. The characteristics of Tee junction are, 1. A short circuit can be positioned in one of the arms of 3 port junction in the manner that no power is moved through the other two arms.
What is H-plane magic tee?
An E-H Plane Tee junction is formed by attaching two simple waveguides one parallel and the other series, to a rectangular waveguide which already has two ports. This is also called as Magic Tee, or Hybrid or 3dB coupler.
