Attenuators: ATT-0219-60-NNN-02 application field and working principle

An attenuator is an electronic device used to reduce the level of electrical signal strength between two points in a transmission line. Typically, an attenuator is inserted between a signal source and load to reduce the power that is transferred. The ATT-0219-60-NNN-02 is a 2 Watt “Square Housing” variable attenuator designed for general purpose applications in the frequency range from 50 MHz to 1 GHz.

Application Field

The ATT-0219-60-NNN-02 attenuator can be used in numerous applications, such as telecommunications and RF/microwave radio frequency systems, commercial and amateur radio communication, military aerospace extreme harsh environment military systems, and more. Additionally, the ATT-0219-60-NNN-02 is useful for production testing, instrumentation, calibration, and other related electronic testing and measurement applications.

Working Principle

The ATT-0219-60-NNN-02 is a linear attenuator that uses a small variable resistor, usually a four-terminal device, to decrease the power of the signal. The resistor is mounted in a square housing for the purpose of keeping it mechanically stable while being adjusted. The resistor is sealed in the housing. The attenuation is wide range and programmable. The basic principles of operation are similar to other types of variable-resistor attenuators, such as the L-pad circuit, which use a moveable arm to adjust the value of a resistor in series with the signal source.The internal construction of the ATT-0219-60-NNN-02 allows for a wide range of resistance values to be adjusted for the purpose of providing a large range of attenuation. The resistance is raised by increasing the applied voltage to the arm on the resistor, while the resistance is lowered by decreasing the applied voltage. The voltage to the arm is adjusted using a combination of a printed circuit board mounted vernier potentiometer and a shaft encoder which are both connected to the resistor arm. The shaft encoder provides resistance value-in-dB feedback to the attenuator\'s control circuit.

Performance Characteristics

The ATT-0219-60-NNN-02 operates with a frequency range of 50 MHz to 1 GHz, and can provide an attenuation range of 5 to 73 dB, with an settling time of 2 ms and a control resolution of 0.1 dB. It can be operated in a temperature range from -40° to 85°C. The terminal impedance of the ATT-0219-60-NNN-02 is 50 ohm, with a VSWR of 1.4:1 maximum. The maximum power rating is 2 Watts, and the maximum input and output VSWR is 1.4:1 and 1.3:1 respectively. The mechanical structure of the ATT-0219-60-NNN-02 is sealed to prevent exposure to dust, dirt, and other debris.

Conclusion

The ATT-0219-60-NNN-02 is a highly reliable and durable device that can be used in a wide range of applications. Its wide range of resistance values and fast settling time make it a great choice for a variety of measurement and testing applications. The attenuator is sealed in its housing which provides enhanced protection from dust, dirt, and other environmental particles. The wide range of resistance values and its frequency range make it a great choice for numerous applications in the telecommunications and RF/microwave radio frequency systems.
