VSWR, rugi bali (RL), daya sing dipantulake, lan daya sing dikirim

Hubungan antarane Voltage Standing Wave Ratio (VSWR), return loss (RL), daya pantulan, lan daya sing dikirim saling gegandhengan liwat koefisien pantulan (Γ). Ing ngisor iki rumus lan langkah-langkah kunci kanggo konversi:

### **Formula Inti**
1. **Koefisien Refleksi (Γ)**:

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

2. **VSWR** saka Γ:

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

3. **Kerugian Balik (RL)** ing dB:

RL (dB) = -20 (|Gamma|)

4. **Daya sing Dipantulake (%)**:

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

5. **Daya sing Ditransmisikake (%)**:

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

### **Langkah-langkah Konversi**
#### **1. Miwiti nganggo VSWR**:
- Ngitung Γ:

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

- Gunakake Γ kanggo nemokake RL, daya pantulan, lan daya sing dikirim nggunakake rumus ing ndhuwur.

#### **2. Miwiti karo Return Loss (RL ing dB)**:
- Ngitung Γ:

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

- Gunakake Γ kanggo nemokake VSWR, daya pantulan, lan daya sing dikirim.

#### **3. Miwiti nganggo Daya sing Dipantulke/Ditransmisikake**:
- Kanggo **daya sing dipantulke** (\(P_{\text{refl}}\)):

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

- Kanggo **daya sing dikirim** (\(P_{\text{trans}}\)):

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

- Gunakna Γ kanggo ngitung VSWR lan RL.

### **Conto Tabel**
| **VSWR** | **Mundhut Bali (dB)** | **Daya Pantulan (%)** | **Daya sing Ditransmisikan (%)** |
|---------|---------------- ...--|
| 1.0 | ∞ (Cocokan sampurna) | 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% |

### **Cathetan Penting**
- **VSWR 1:1** tegese ora ana pantulan (Γ = 0, RL = ∞).
- **VSWR sing luwih dhuwur** utawa **RL** sing luwih endhek nuduhake daya pantulan sing luwih akeh.
- **Daya sing ditransmisikake** dimaksimalake nalika VSWR ≈ 1.
