VSWR, te ngaronga whakahoki (RL), te mana whakaata, me te mana tuku

Ko ngā whanaungatanga i waenga i te Tauwehenga Ngaro Tū Ngaohiko (VSWR), te ngaronga whakahoki (RL), te mana whakaata, me te mana tuku e hono tahi ana mā te tauwehenga whakaata (Γ). Kei raro nei ngā tātai matua me ngā mahi mō te tahuritanga:

### **Ngā Tātai Matua**
1. **Whakaaro Whakaata (Γ)**:

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

2. **VSWR** mai i Γ:

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

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

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

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

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

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

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

### **Ngā Hipanga Tahuri**
#### **1. Tīmata ki te VSWR**:
- Tātaihia a Γ:

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

- Whakamahia te Γ hei kimi i te RL, te mana whakaata, me te mana tuku mā te whakamahi i ngā tātai i runga ake nei.

#### **2. Tīmata ki te Ngaronga Whakahoki (RL i roto i te dB)**:
- Tātaihia a Γ:

|\Kama| = 10^{-\kuputuhi{RL}/20}

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

#### **3. Tīmata ki te Mana Whakaata/Tukuna**:
- Mō te **mana whakaata** (\(P_{\text{refl}}\)):

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

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

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

- Whakamahia a Γ hei tatau i te VSWR me te RL.

### **Tauira Ripanga**
| **VSWR** | **Ngaronga Whakahoki (dB)** | **Mana Whakaata (%)** | **Mana Tuku (%)** |
|----------|---------------- ...-|
| 1.0 | ∞ (Taurite 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% |

### **Ngā Tuhipoka Matua**
- Ko te **VSWR o te 1:1** te tikanga kāore he whakaata (Γ = 0, RL = ∞).
- **Ko te VSWR teitei** te **RL iti** rānei e tohu ana i te mana whakaata nui ake.
- Ka whakanuia te **mana tuku** ina VSWR ≈ 1.

Whakamahia ēnei tātai hei whakawhiti i waenga i ngā tawhā mō te taurite aukati i roto i ngā pūnaha RF.
