RF Attenuators

RF Attenuators

RF Attenuators are components that reduce the amplitude level of an incoming frequency signal. They are used to protect systems from receiving a signal with a power level that is too high to process. There are various types of attenuators that can fit your engineering needs. Precision MMW will help you with the highest quality RF attenuator products needs. We are a millimeter wave spectrum manufacturer of various active and passive mmWave products and sub-system engineering.

When selecting an RF attenuator it is important to know the specifications needed. Things like:

Attenuation: This is the level of attenuation that your specs need. If you are looking for a fixed attenuator, then this would be a single attenuation level in dB. However, if you are looking for a variable attenuator then this would be an attenuation range that you want to work with.

Attenuation Accuracy: This is the level by which the attenuation level can vary.

Frequency: This is the frequency range over which the attenuator can operate while maintaining its electrical characteristic i.e Attenuation level, VSWR etc. The attenuation level usually varies over the frequency band of interest. It is important to see the attenuation response over the frequency band of a product.

Impedance: Attenuators are designed to operate with a characteristic impedance of 50 Ohms. There are models where 75 Ohms attenuators are common. Make sure you are matching the characteristic impedance of the attenuator to that of the system/circuity where it will be used. This will minimize reflections.
