Main technical specifications of china 4 4 hybrid combiner from khedmehcom's blog

The china 4 4 hybrid combiner is a passive component that is widely used in electronic circuits to reduce the amplitude of signals. In practical applications, the performance of china 4 4 hybrid combiner has a very important impact on the stability and signal quality of the circuit.

The main technical specifications of china 4 4 hybrid combiner are as follows:

1. Attenuation quantity

Attenuation is an important index to measure the performance of china 4 4 hybrid combiner. It represents the amplitude attenuation of china 4 4 hybrid combiner to the signal. The amount of attenuation is usually expressed in decibels (dB) and calculated by the formula: A(dB) = 10lg(P2/P1), where P1 and P2 represent the power of the input signal and the output signal, respectively. In practical applications, the size of the attenuation needs to be determined according to the requirements of the circuit. Generally, the attenuation is required to keep stable within a certain frequency range. At the same time, the signal distortion and noise and other factors need to be considered.

2. Frequency range

The frequency range of the china 4 4 hybrid combiner refers to the frequency range in which it can operate effectively. When designing and selecting the china 4 4 hybrid combiner, determine the frequency range of the china 4 4 hybrid combiner according to the operating frequency range of the circuit. If the frequency range of the china 4 4 hybrid combiner is not wide enough, it will cause problems such as distortion and uneven attenuation of the signal during transmission.

3. Insertion loss

Insertion loss refers to the loss of signal amplitude caused by china 4 4 hybrid combiner during operation. The smaller the insertion loss, the less attenuation the china 4 4 hybrid combiner will have on the signal and the better the signal quality. In practical application, the china 4 4 hybrid combiner with low insertion loss should be selected according to the requirements of the circuit.

4. Standing Wave ratio

Standing wave ratio refers to the ratio of reflection coefficient between input and output of china 4 4 hybrid combiner, which reflects the matching degree of china 4 4 hybrid combiner. When the standing wave ratio is 1, the input and output of the china 4 4 hybrid combiner match exactly. In this case, the performance of the china 4 4 hybrid combiner is optimal. If the standing wave ratio is too large, it will cause the reflection and loss of the signal, which will affect the transmission quality of the signal.

5. Temperature coefficient

Temperature coefficient refers to the degree to which the attenuation of china 4 4 hybrid combiner changes with temperature. In practical applications, the performance of the china 4 4 hybrid combiner will also change due to changes in ambient temperature. Therefore, china 4 4 hybrid combiner with low temperature coefficient should be selected to ensure its stability at different temperatures.

6. Bandwidth

Bandwidth refers to the frequency range in which the china 4 4 hybrid combiner can work. In practical applications, china 4 4 hybrid combiner with appropriate bandwidth should be selected according to circuit requirements to ensure its stability and signal quality at different frequencies.

When selecting and designing the china 4 4 hybrid combiner, you need to set these values based on the circuit requirements to ensure the performance and stability of the china 4 4 hybrid combiner.
