VSWR, nkwụghachi azụ (RL), ike egosipụtara, na ike ebufe

Mmekọrịta dị n'etiti Voltage Standing Wave Ratio (VSWR), nkwụghachi azụ (RL), ike egosipụtara, na ike ebufe na-ejikọta ọnụ site na ngbanwe ntụgharị (Γ). N'okpuru bụ isi usoro na usoro maka ntụgharị:

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

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

2. **VSWR** sitere na Γ:

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

3. ** Nlaghachi azụ (RL)** na dB:

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

4. **Ike egosipụtara (%) ***:

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

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

P_{\text{trans}} = \ aka ekpe (1 - |\Gamma|^2\nri) \ ugboro 100\%

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

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

- Jiri Γ chọta RL, ike egosipụtara na ike ebufe site na iji usoro dị n'elu.

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

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

- Jiri Γ chọta VSWR, ike egosipụtara na ike ebufe.

#### **3. Malite na ike egosipụtara/ebufefere**:
- Maka ** ike egosipụtara ** (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.

### ** Okpokoro Ọmụmaatụ**
| **VSWR** | ** Nlaghachi (dB)** | ** Ike egosipụtara (%) *** | ** Ike ebufere (%) *** |
|-----------------------------------------|------------------------------------|-------------|
| 1.0 | ∞ (Egwuregwu 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% |

### ** ndetu isi**
- A ** VSWR nke 1: 1 ** pụtara enweghị echiche (Γ = 0, RL = ∞).
- ** VSWR dị elu ma ọ bụ ** RL dị ala na-egosi ike egosipụtara karịa.
* A na-ebuli ike mbufe ** mgbe VSWR ≈ 1.

Jiri usoro ndị a tụgharịa n'etiti parampat maka ndakọrịta mgbochi na sistemu RF.
