• 电路中或传输线上的阻抗失配会产生反射,回到信号源。 • 当信号反射时,向末端负载传输的功率就会减少。 • 阻抗匹配发挥了一种双重作用,即通过抑制反射使功率传输到负载。 每当电磁信号沿着传输线传播时,都有可能从传输线和负载器件之间的接口上反射回来。负载可以是任何东西:另一段传输线、集成电路、天线....

英文:Impedance mismatch can lead to energy reflection and signal distortion. 英文同义表达: Resistance and reactance together (阻抗是电阻和电抗的综合体) 解释:阻抗由实部(电阻)和虚部(电抗)组成,表示电路对交流电的总体阻碍。 Complex impedance (复数阻抗) 解释...
Impedance mismatch can lead to signal reflection and inefficient power transfer. These reflections cause destructive interference, leading to peaks and valleys in the voltage. Impedance matching is therefore important to obtain a desirable VSWR (voltage standing wave ratio). ...
3. load impedance The intensity of the load reflected signal depends on the mismatch between the signal source impedance and the load impedance. The expression for the reflection coefficient is defined as: Since the impedance is complex, the coefficient of reflection is also plural. To reduce the...
Fresnel reflections occur at material interfaces due to impedance mismatch, with reflectivity calculated using Fresnel equations.
This reduction is partially originated from the energy consumption in the circuit, and partially originated from the electrical impedance mismatch between the circuit output (still around 5 kΩ) and the rechargeable battery impedance (around 10–50 Ω). The circuit losses include (1) conduction ...
Mismatch Loss = –10 log(1 –ρ2) Whereρis the reflection coefficient. For example, a filter with VSWR of 2:1 would have a reflection coefficient of 0.333, a mismatch loss of 0.51 dB, and a return loss of 9.54 dB (11% of the transmitted power is refl...
