Digital Step Attenuator
Ranatec’s digital attenuators Ranatec’s digital attenuators are used to accurately and reliably set RF-signal levels, either as an integral part of an in-service RF-solution or as part of a wireless test automation system. Applications span multiple industries and technologies.
Controlling the level of the RF signal with a digital step attenuator is a must to:
- Secure compliance with standards and regulations (and to avoid unhealthy radiation)
- Avoid hardware malfunctions and damages due to excessive RF levels
- Optimize the performance of networks, receivers, transmitters, and other RF functions
Ranatec has developed a range of wireless test automation products, enabling accurate and efficient test and verification of RF and microwave subsystems, products and solutions. The Ranatec test automation product range contains both general purpose instruments as well as solutions tailored to customer specific demands and are used for design validation and verification, homologation and certification as well as production testing and in-service monitoring.

FAQs
A digital attenuator is a device that attenuates or reduces the amplitude of an RF signal passing through it – where the amount of attenuation is digitally controlled. The main purpose of a digital attenuator is to set RF signal levels for testing and verification of RF and microwave subsystems, products, and solutions.
There’s several important parameters you need to keep in mind when you’re on the lookout for digital step attenuators solutions. These are important considerations you need to keep in mind to be able to find the right digital attenuator to match your needs:
- The operating frequency at which the digital attenuator is either fully functional or provides the best performance.
- The total attenuation range that the attenuator can provide.
- Attenuation step size, typically 0.25, 0.5 or 1.0 dB. This defines the smallest change in attenuation that can be achieved.
- Insertion loss. This is the smallest attenuation that can be set.
- The type of logic the digital attenuator uses to perform attenuation.
- The switching speeds for how long it takes the attenuator to switch between two states. Interface compatibility.
A digital step attenuator and digital attenuator are the same thing. A digital attenuator, unlike variable attenuators, switches in discrete and finite attenuation states, usually achieved in binary steps, employing semiconductor devices to achieve each attenuation step. Due to how it sets the attenuation levels, a digital attenuator is often referred to as a digital step attenuator.
