I-VSWR, ilahleko yokubuyisela (RL), amandla abonakalisiweyo, kunye nokuhanjiswa kwamandla

Ubudlelwane phakathi kweVoltage Standing Wave Ratio (VSWR), imbuyekezo yelahleko (RL), amandla abonakalisiweyo, kunye namandla athunyelwayo aqhagamshelwe nge-coefficient yokubonisa (Γ). Ngezantsi ziifomula eziphambili kunye namanyathelo okuguqula:

### **Iifomula eziphambili**
1. **I-Reflection Coefficient (Γ)**:

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

2. **VSWR** esuka kwi-Γ:

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

3. **Buyisela Ilahleko (RL)** kwi-dB:

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

4. **Amandla abonakalisiweyo (%)**:

P_{\ okubhaliweyo{refl}} = |\Gamma|^2 \ amaxesha 100\%

5. **Amandla aThunyelweyo (%)**:

P_{\ okubhaliweyo{trans}} = \ ekhohlo(1 - |\Gamma|^2\ekunene) \ amaxesha 100\%

### **Amanyathelo oGuqulo**
#### **1. Ukuqala ngeVSWR**:
- Bala i-Γ:

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

-Sebenzisa i-Γ ukufumana iRL, amandla abonakalisiweyo, kunye nokuhanjiswa kwamandla usebenzisa iifomyula ezingentla.

#### **2. Ukuqala ngeLahleko yokuBuyisa (RL kwi-dB)**:
- Bala i-Γ:

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

-Sebenzisa i-Γ ukufumana i-VSWR, amandla abonakalisiweyo, kunye nokuhanjiswa kwamandla.

#### **3. Ukuqala Ngamandla abonakalisiweyo/aThunyelweyo**:
-Ku **amandla abonakalisiweyo** (\(P_{\text{refl}}\)):

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

- Nge **amandla athunyelwayo** (\(P_{\text{trans}}\)):

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

-Sebenzisa i-Γ ukubala i-VSWR kunye ne-RL.

### **Umzekelo weTheyibhile**
| **VSWR** | **Buyisela Ilahleko (dB)** | **Amandla abonakalisiweyo (%)** | **Amandla aThunyelweyo (%)** |
|----------|-------------------------------------------------------------------------------
| 1.0 | ∞ (Umdlalo ogqibeleleyo) | 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% |

---

### **Amanqaku angundoqo**
- A **VSWR ka-1:1** ithetha ukungabonisi (Γ = 0, RL = ∞).
- **I-VSWR ephezulu** okanye **i-RL esezantsi** ibonisa amandla abonakalisiweyo ngakumbi.
- **Amandla athunyelwayo** enziwa maninzi xa i-VSWR ≈ 1.

Sebenzisa ezi fomyula ukuguqula phakathi kweeparamitha zokuthelekisa i-impedance kwiinkqubo zeRF.
