What is voltage controlled attenuator?
A voltage variable attenuator is an electronic device that provides a variable attenuation depending on the voltage applied. Unlike fixed attenuators whose attenuation cannot be adjusted by a user, the attenuation levels of variable attenuators can be changed to desired values.
What is the purpose of the attenuator control?
In measuring signals, attenuator pads or adapters are used to lower the amplitude of the signal a known amount to enable measurements, or to protect the measuring device from signal levels that might damage it.
What is a SMA attenuator?
SMA Fixed Attenuators. Pasternack SMA fixed attenuators have an attenuation range that is from 0 dB to 60 dB. The frequency range of our SMA fixed attenuators is from DC to 26 GHz. This SMA attenuator product line includes low to high power attenuators which have the power handling up to 100 Watts.
How do you attenuate a signal?
If you turn the volume down on your radio, it’s reducing the amplification of the signal, not attenuating it. The same signal may be attenuated by a filter that removes all unwanted signals above a certain frequency.
How does a voltage controlled amplifier work?
How does it work? A VCA is an amplifier, which usually accepts bipolar signal at its carrier or signal input and a uni-polar positive signal at its modulator or control input. Furthermore, the output signal is the instantaneous product of both of these signals.
Where attenuators are mainly used?
Attenuators are generally used in radio, communication and transmission line applications to weaken a stronger signal. Resistive attenuators are used as volume controls in broadcasting stations and also can be used for matching circuits of different resistive impedances.
What is RF attenuator?
RF attenuators are essentially electrical resistors that are put in line with an RF signal and reduce the signal strength by converting some amount of RF energy into heat. The amount of resistance used is what determines the amount of attenuation.
Are attenuators bad for amps?
Electrically speaking, it would make no real sense for an attenuator to damage an amplifier considering these devices come after the amp in the signal chain. Problems do arise when players implement attenuators, but more often than not it is a result of having the amp pushed to its limits for hours at a time.
How do I connect my attenuator to my amp?
To use an attenuator, connect a speaker cable from one of your amp’s speaker outputs to the attenuator’s input, and then connect another speaker cable from the attenuator’s output or through jack to the speaker cabinet’s input jack.

What is the insertion loss of a power splitter?
The power combiner will exhibit an insertion loss that varies depending upon the phase and amplitude relationship of the signals being combined. For example, in a 2 way 0° power splitter/combiner (Figure 1), if the two input signals are equal in amplitude and are in-phase then the insertion loss is zero.
