VSWR, asarar dawowa (RL), wutar lantarki mai nuna haske, da wutar lantarki da aka watsa

Alaƙa tsakanin Ratio na Tsayayyen Wutar Lantarki (VSWR), asarar dawowa (RL), ƙarfin da aka nuna, da kuma wutar da aka watsa suna da alaƙa ta hanyar ma'aunin haske (Γ). Ga manyan dabarun da matakai don canzawa:

### **Tsarin Tsarin Gine-gine**
1. ** Tunani Coefficient (Γ) ***:

\Gamma = \frac{\rubutu{VSWR} - 1}{\rubutu{VSWR} + 1}

2. **VSWR** daga Γ:

\text{VSWR} = \frac{1 + |\Gamma|}{1 - |\Gamma|}

3. **Rashin Dawowa (RL)** a cikin dB:

\text{RL (dB)} = -20 \log_{10}(|\Gamma|)

4. **Ƙarfin da Aka Nuna (%)**:

P_{\text{refl}} = |\Gamma|^2 \sau 100\%

5. **Ikon da aka watsa (%)**:

P_{\text{trans}} = \left(1 - |\Gamma|^2\right) \times 100\%

### **Matakai na Canzawa**
#### **1. Farawa da VSWR**:
- Lissafa Γ:

\Gamma = \frac{\rubutu{VSWR} - 1}{\rubutu{VSWR} + 1}

- Yi amfani da Γ don nemo RL, ƙarfin da aka nuna, da kuma ikon da aka watsa ta amfani da dabarun da ke sama.

#### **2. Farawa da Rasa Dawowa (RL a cikin dB)**:
- Lissafa Γ:

|\Gamma| = 10^{-\text{RL}/20}

- Yi amfani da Γ don nemo VSWR, ƙarfin da aka nuna, da kuma wutar da aka watsa.

#### **3. Farawa da Ƙarfin Mai Hankali/Ana Gudarwa**:
- Don **ikon da aka nuna** (\(P_{\text{refl}}\)):

|\Gamma| = \sqrt{\frac{P_{\text{refl}}}{100}}

- Don **ikon da aka watsa** (\(P_{\text{trans}}\)):

|\Gamma| = \sqrt{1 - \frac{P_{\text{trans}}}{100}}

- Yi amfani da Γ don ƙididdige VSWR da RL.

### **Bayanan Muhimman Bayanai**
- A **VSWR na 1:1** yana nufin babu tunani (Γ = 0, RL = ∞).
- **VSWR mafi girma** ko **ƙasa RL** yana nuna ƙarin ƙarfin da aka nuna.
- **Ana ƙara ƙarfin watsawa** lokacin da VSWR ≈ 1 ya yi yawa.
