VSWR, mfu nloghachi (RL), ike gosipụtara, na ike ebufere

Mmekọrịta dị n'etiti Voltaji Standing Wave Ratio (VSWR), Return Loss (RL), return power, na transmission power jikọtara site na reflection coefficient (Γ). N'okpuru ebe a bụ usoro na usoro maka ntụgharị:

### **Usoro Isi**
1. **Ntụgharị uche (Γ)**:

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

2. **VSWR** site na Γ:

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

3. **Mfu nloghachi (RL)** na dB:

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

4. **Ike A Na-egosipụta (%)**:

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

5. **Ike Ebufere (%)**:

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

### **Nzọụkwụ Ntụgharị**
#### **1. Malite na VSWR**:
- Gbakọọ Γ:

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

- Jiri Γ chọta RL, ike e gosipụtara, na ike ebufere site na iji usoro ndị dị n'elu.

#### **2. Malite na Mfu Nlaghachi (RL na dB)**:
- Gbakọọ Γ:

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

- Jiri Γ chọta VSWR, ike a na-egosipụta, na ike ebufere.

#### **3. Malite na Ike Reflected/Transmitted**:
- Maka **ike a na-egosipụta** (\(P_{\text{refl}}\)):

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

- Maka **ike ebufere** (\(P_{\text{trans}}\)):

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

- Jiri Γ gbakọọ VSWR na RL.

### **Tebụl Ihe Nlereanya**
| **VSWR** | **Mfu nloghachi (dB)** | **Ike A Na-egosipụta (%)** | **Ike Ebufere (%)** |
|-----------|----------------------------|----------------------------|----------------------------|
| 1.0 | ∞ (Njikọ zuru oke) | 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% |

### **Ihe Ndị Dị Mkpa**
- A **VSWR nke 1:1** pụtara enweghị ntụgharị uche (Γ = 0, RL = ∞).
- **VSWR dị elu** ma ọ bụ **RL dị ala** na-egosi ike a na-egosipụta karịa.
- **A na-eme ka ike ebufere** dịkwuo elu mgbe VSWR ≈ 1.

Jiri usoro ndị a gbanwee n'etiti paramita maka ndakọrịta impedance na sistemụ RF.
