I-VSWR, ilahleko yokubuya (RL), amandla abonakalisiweyo, kunye namandla adluliselweyo

Ubudlelwane phakathi kweVoltage Standing Wave Ratio (VSWR), iReturn loss (RL), amandla abonakalisiweyo, kunye namandla adluliselweyo budibene ngeReflection coefficient (Γ). Apha ngezantsi kukho iifomyula eziphambili kunye namanyathelo okuguqula:

### **Iifomula eziPhambili**
1. **I-Reflection Coefficient (Γ)**:

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

2. **VSWR** ukusuka kwi-Γ:

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

3. **Ilahleko yokubuyisela (RL)** kwi-dB:

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

4. **Amandla Abonakalisiweyo (%)**:

P_{\text{refl}} = |\Gamma|^2 \izihlandlo eziyi-100\%

5. **Amandla aThunyelwayo (%)**:

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

### **Amanyathelo okuguqula**
#### **1. Ukuqala nge-VSWR**:
- Bala i-Γ:

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

- Sebenzisa u-Γ ukuze ufumane i-RL, amandla abonakalisiweyo, kunye namandla adluliselweyo usebenzisa iifomyula ezingasentla.

#### **2. Ukuqala ngeReturn Loss (RL kwi-dB)**:
- Bala i-Γ:

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

- Sebenzisa u-Γ ukuze ufumane i-VSWR, amandla abonakalisiweyo, kunye namandla adluliselweyo.

#### **3. Ukuqala Ngamandla Abonakalisiweyo/Adluliswayo**:
- Nge **amandla abonakalisiweyo** (\(P_{\text{refl}}\)):

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

- Nge **amandla adluliselweyo** (\(P_{\text{trans}}\)):

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

- Sebenzisa i-Γ ukubala i-VSWR kunye ne-RL.

### **Itheyibhile yoMzekelo**
| **VSWR** | **Ilahleko yokubuyisela (dB)** | **Amandla abonakalisiweyo (%)** | **Amandla adlulisiweyo (%)** |
|--------|- ...----|
| 1.0 | ∞ (Umdlalo ogqibeleleyo) | 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% |

### **Amanqaku aphambili**
- I-**VSWR ye-1:1** ithetha ukuba akukho kubonakaliswa (Γ = 0, RL = ∞).
- **I-VSWR ephezulu** okanye **i-RL esezantsi** ibonisa amandla abonakalayo ngakumbi.
- **Amandla adluliselwayo** andiswa kakhulu xa i-VSWR ≈ 1.

Sebenzisa ezi fomula ukuguqula phakathi kweeparamitha zokudibanisa i-impedance kwiinkqubo zeRF.
