An attenuator, sometimes referred to as a variable attenuator, is a device that controls the amount of signal power that passes through it. The ATT-0389-30-NNN-02 is a variable attenuator designed to attenuate RF signals in the frequency range of 10 to 1000 MHz. The attenuation range of the device is from 0 to 30dB. It can also be used for signal monitoring and for providing impedance matching in test setups.

Application Field

The ATT-0389-30-NNN-02 is a variable RF amplifier suitable for a variety of applications. It can be used in test and measurement setups to measure the strength of a signal, and for frequency analysis and signal power control. It can also be used in laboratory settings to attenuate RF signals with the desired amount of signal power.

The device is also suitable for power supplied by 9V batteries, making it ideal for field or portable applications. It can be used in a variety of wireless technologies, such as bluetooth, Wi-Fi, GPS, and radio. Additionally, it can be used to match impedance between circuit elements in various types of wireless systems.

Working Principle

The ATT-0389-30-NNN-02 utilizes an adjustable attenuator circuit to continuously vary the signal power applied to the device. When the device is de-energized, the attenuator disconnects the input signal from the device, thereby attenuating the signal. When the device is energized, the attenuator circuit allows a portion of the signal to be attenuated in accordance with the settings of the device.

The device has two separate levels of power available for use. The first level of power is a low power mode which is intended for low power signals. In this mode, the attenuator circuit can provide up to 0 to 30dB of attenuation. The second level of power is a higher power mode which is used for RF signals of higher power levels. This mode provides more than 40dB of attenuation.

The device is also equipped with an adjustable control knob which can be used to adjust the amount of attenuation applied to the signal. The control knob can be used to adjust the amount of attenuation in a range from 0 to 30dB. In addition, there is an indicator light which indicates when the device is in a high-power mode and when the device is in a low-power mode.

Conclusion

The ATT-0389-30-NNN-02 is a variable RF amplifier designed to attenuate RF signals in the frequency range of 10 to 1000 MHz. It has two levels of power available for use and can provide up to 0 to 30dB of attenuation in low power mode and more than 40dB of attenuation in high power mode. The adjustable control knob can be used to adjust the amount of attenuation applied to the signal and an indicator light indicates when the device is in a high-power mode. The device is suitable for a variety of applications including test and measurement setups, frequency analysis, signal power control, and impedance matching in wireless systems.
