VSWR, te hokinga mai (RL), te mana whakaata, me te mana tuku

Ko nga hononga i waenga i te Ngaohiko Tuturu Ngaru Ratio (VSWR), te hokinga mai (RL), te hiko whakaata, me te hiko tuku e hono ana ma te whakarea whakaata (Γ). Kei raro nei nga tauira matua me nga kaupae mo te hurihanga:

### **Tatai Matua**
1. **Whakaaro Whakaata (Γ)**:

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

2. **VSWR** mai i Γ:

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

3. **Whakahoki Ngaronga (RL)** i te dB:

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

4. **Te Mana Whakaata (%)**:

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

5. **Te Mana Tuku (%)**:

P_{\text{trans}} = \maui(1 - |\Gamma|^2\matau) \wa 100\%

### **Taahiraa Tahuri**
#### **1. Ka tiimata me te VSWR**:
- Tatauhia Γ:

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

- Whakamahia te Γ hei kimi i te RL, te hiko whakaata, me te hiko tuku ma te whakamahi i nga tauira o runga.

#### **2. Ka timata me te Whakahoki Ngaronga (RL i te dB)**:
- Tatauhia Γ:

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

- Whakamahia te Γ ki te kimi VSWR, te mana whakaata, me te mana tuku.

#### **3. Ka timata me te Mana Whakaata/Whakawhitia**:
- Mo **te mana whakaata** (\(P_{\text{refl}}\)):

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

- Mo **te mana tuku** (\(P_{\text{trans}}\)):

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

- Whakamahia te Γ hei tātai i te VSWR me te RL.

### **Taira Tauira**
| **VSWR** | **Whakahoki Ngaronga (dB)** | **Te Mana Whakaata (%)** | **Te Mana Tukua (%)** |
|----------|----------------------|------------------------|-------------------------|
| 1.0 | ∞ (Whakaritenga tino pai) | 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% |

### **Tuhinga Matua**
- Ko te **VSWR o 1:1** te tikanga kaore he whakaata (Γ = 0, RL = ∞).
- ** VSWR teitei ake ** ranei ** RL raro ** e tohu ana i te kaha ake o te whakaata.
- **Ka whakanuia te mana tuku** ina VSWR ≈ 1.
