VSWR, kudzoka kurasikirwa (RL), inoratidzira simba, uye simba rinopfuudzwa

Hukama huri pakati peVoltage Standing Wave Ratio (VSWR), kurasikirwa kwekudzoka (RL), simba rinoratidzwa, uye simba rinopfuudzwa zvakabatanidzwa kuburikidza neanoratidza coefficient (Γ). Pazasi pane mafomula akakosha uye matanho ekushandura:

### **Core Formulas**
1. **Reflection Coefficient (Γ)**:

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

2. **VSWR** kubva kuΓ:

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

3. **Dzorera Kurasika (RL)** mu dB:

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

4. **Reflected Power (%)**:

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

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

P_{\text{trans}} = \kuruboshwe(1 - |\Gamma|^2\kurudyi) \nguva 100\%

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

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

-Shandisa Γ kutsvaga RL, inoratidzira simba, uye simba rinopfuudzwa uchishandisa mafomula ari pamusoro.

#### **2. Kutanga neKudzokera Kurasika (RL mu dB)**:
- Verenga Γ:

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

-Shandisa Γ kutsvaga VSWR, inoratidzira simba, uye simba rinopfuudzwa.

#### **3. Kutanga neReflected/Transmitted Power**:
-Ku**simba rakaratidzwa** (\(P_{\text{refl}}\)):

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

-Ku**simba rinofambiswa** (\(P_{\text{trans}}\)):

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

-Shandisa Γ kuverengera VSWR uye RL.

### **Muenzaniso Tafura**
| **VSWR** | **Dzorera Kurasika (dB)** | **Reflected Power (%)** | **Kufambiswa Simba (%)** |
|---------------------------------------------------------------------------------------|
| 1.0 | ∞ (Mutambo wakakwana) | 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% |

### **Manyotsi Akakosha**
- A **VSWR ye1:1** zvinoreva kusaratidza (Γ = 0, RL = ∞).
- ** Yepamusoro VSWR ** kana ** yakaderera RL ** inoratidza mamwe anotaridza simba.
- **Simba rinofambiswa ** rinowedzerwa kana VSWR ≈ 1.

Shandisa aya mafomula kuchinjisa pakati pema paramita e impedance yekufananidza muRF masisitimu.
