What are the relevant parameters of the attenuator?

1) Attenuation: Used to describe the magnitude of the signal reduction from one end to the other during transmission. It can be expressed in multiples or decibels.

2)VSWR: equal to the ratio of the characteristic impedance to the load impedance connected to the output of the transmission line.

3) Maximum average power: When the output terminal of the attenuator is connected to the characteristic impedance, the maximum power that can be added to the input terminal of the attenuator for a long time at the specified high operating temperature. When the operating temperature drops to 20 degrees and the input power drops to 10mW, the other indicators of the attenuator should not change.

4) Power coefficient of insertion loss: When the input power is from 10mW to the rated power, the change value of insertion loss (dB).

5) Maximum peak power: When the output of the attenuator is connected to the characteristic impedance, the maximum peak power of the 5ms pulse width added to the input of the attenuator at the specified high operating temperature and within the specified time. When the operating temperature drops to 20 degrees and the input power drops to 10mW, the other indicators of the attenuator should not change.

6) Temperature coefficient: a great change in insertion loss over a great operating temperature range.
