- analog attenuation values from 15 to 40 dB
|digital attenuators||voltage variable (analog) attenuators|
Fixed and Step attenuators
|Attenuators are used in a wide variety of applications and can satisfy almost any requirement where a reduction in power is needed.
Attenuators are used to extend the dynamic range of devices such as power meters and amplifiers, reduce signal levels to detectors, match circuits and are used daily in lab applications to aid in product design.
Attenuators are also used to balance out transmission lines that otherwise would have unequal signal levels.
|Fixed Attenuators 2 Watt||Fixed Attenuators 5 – 50 Watt|
|Fixed Attenuators 100 – 150 Watt||Variable Step Attenuators|
HF Abschlüsse (Terminations/Load):
|Terminations, or loads, are matched to 50 ohms characteristic impedance. Matched loads provide a termination designed to absorb all the incident power with very little reflection, effectively terminating the line or port in its characteristic impedance.
Terminations are used in a wide variety of measurement systems; any port of a multi-port microwave device that is not involved in the measurement should be terminated in its characteristic impedance in order to ensure an accurate measurement.
Terminations are also used in devices such as directional couplers and isolators. High power versions are used in transmitter applications as dummy loads. .
|Terminations 1- 2 Watt||Terminations 5 – 25 Watt|
|Terminations 35 – 500 Watt|
