VSWR, kurasikirwa nekudzoka (RL), simba rinoratidzwa, uye simba rinotumirwa

Hukama huripo pakati peVoltage Standing Wave Ratio (VSWR), return loss (RL), reflective power, uye transmission power zvakabatana kuburikidza ne reflection coefficient (Γ). Heano maformula akakosha nematanho ekushandura:

### **Mafomura Akakosha**
1. **Reflection Coefficient (Γ)**:

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

2. **VSWR** kubva kuΓ:

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

3. **Kurasikirwa Kwekudzoka (RL)** mu dB:

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

4. **Simba Rinoratidzwa (%)**:

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

5. **Simba Rinotumirwa (%)**:

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

### **Matanho Ekushandura**
#### **1. Kutanga neVSWR**:
- Verenga Γ:

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

- Shandisa Γ kuti uwane RL, simba rinoratidzwa, uye simba rinotumirwa uchishandisa mafomula ari pamusoro.

#### **2. Kutanga neReturn Loss (RL mu dB)**:
- Verenga Γ:

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

- Shandisa Γ kuti uwane VSWR, simba rinoratidzwa, uye simba rinotumirwa.

#### **3. Kutanga neSimba Rinoratidzwa/Rinotumirwa**:
- Kune **simba rakaratidzwa** (\(P_{\text{refl}}\)):

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

- Kune **simba rinotumirwa** (\(P_{\text{trans}}\)):

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

- Shandisa Γ kuverenga VSWR neRL.

### **Tafura yemuenzaniso**
| **VSWR** | **Kurasikirwa Nekudzoka (dB)** | **Simba Rinoratidzwa (%)** | **Simba Rinotumirwa (%)** |
|--------|- ...---|
| 1.0 | ∞ (Muenzaniso wakanaka) | 0% | 100% |
| 1.5 | 14.0 dB | 4% | 96% |
| 2.0 | 9.5 dB | 11.1% | 88.9% |
| 3.0 | 6.0 dB | 25% | 75% |

### **Zvinyorwa Zvikuru**
- A **VSWR ye1:1** zvinoreva kuti hapana kuratidzwa (Γ = 0, RL = ∞).
- **VSWR** yakakwira kana **RL yakaderera** inoratidza simba rakawanda rinoratidzwa.
- **Simba rinotumirwa** rinowedzera kana VSWR ≈ 1.

Shandisa mafomati aya kushandura pakati pema parameter ekuenzanisa impedance muma RF systems.
