VSWR, mundhut bali (RL), daya sing dibayangke, lan daya sing dikirim

Hubungan antarane Voltage Standing Wave Ratio (VSWR), return loss (RL), daya pantulan, lan daya sing dipancarake saling nyambungake liwat koefisien refleksi (Γ). Ing ngisor iki rumus utama lan langkah-langkah 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. **Return Loss (RL)** ing dB:

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

4. ** Daya Pantulan (%)**:

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

5. ** Daya Pancar (%)**:

P_{\text{trans}} = \kiwa(1 - |\Gamma|^2\kanan) \kali 100\%

### **Langkah Konversi**
#### **1. Miwiti karo VSWR**:
- Hitung Γ:

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

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

#### **2. Diwiwiti karo Rugi Bali (RL ing dB)**:
- Hitung Γ:

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

- Gunakake Γ kanggo nemokake VSWR, daya sing dibayangke, lan daya sing ditularake.

#### **3. Diwiwiti karo Daya Pantulan/Dikirim**:
- Kanggo **daya sing dibayangke** (\(P_{\text{refl}}\)):

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

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

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

- Gunakake Γ kanggo ngitung VSWR lan RL.

### **Tabel Tuladha**
| **VSWR** | **Bale Mundhut (dB)** | **Daya sing dibayangke (%)** | **Daya Dikirim (%)** |
|----------|----------------------|-----------------------|------------|
| 1.0 | ∞ (Pertandhingan 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 Utama**
- **VSWR saka 1:1** tegese ora ana refleksi (Γ = 0, RL = ∞).
- ** VSWR sing luwih dhuwur ** utawa ** RL ngisor ** nuduhake daya sing luwih dibayangke.
- ** Daya sing ditularake ** maksimal nalika VSWR ≈ 1.

Gunakake rumus iki kanggo interconvert antarane paramèter kanggo impedansi cocog ing sistem RF.
