Coaxial Attenuator is an energy-losing RF/microwave component with a resistive material inside the component. In addition to the commonly used resistive fixed attenuators, there are also electrically controlled fast adjustment attenuators. The attenuator is widely used in a variety of occasions that require power level adjustment.
The technical indicators of the attenuator attenuator technical indicators, including the attenuator's operating band, attenuation, power capacity, return loss, etc..
1, The operating frequency band. The operating band of the attenuator refers to the use of the attenuator in a given frequency range, the attenuator in order to achieve the target value. As the RF / microwave structure and frequency-related, different frequency bands of components, different structures, and can not be generalized. Modern coaxial structure of the attenuator used in the operating band is quite wide, the design or use of attention.
2, The amount of attenuation. Regardless of the formation of power attenuation mechanism and the specific structure of how, always can be used to describe the two-port network attenuator signal input power for P1, and the output side of the power for P2, the attenuator power attenuation for A (dB). If P1 , P2 in decibels milliwatts (dBm), the relationship between the two ends of the power P2 (dBm) = P1 (dBm) - A (dB)
3, Power capacity. The attenuator is an energy-consuming element, power consumption into heat. It is conceivable that the power capacity of the attenuator is determined after the material structure is determined. If the attenuator is allowed to withstand more power than this limit value, the attenuator will be burned. Design and use, must specify the power capacity.
4, Return loss. Return loss is the attenuator standing wave ratio, the requirements of the attenuator at both ends of the input and output standing wave ratio should be as small as possible. We hope that the attenuator is a power-consuming components, can not have an impact on the circuit at both ends, that is, with both ends of the circuit are matched. Consider this factor when designing the attenuator.
