ATT-0290-01-SMA-02

Attenuators are passive electrical components, such as resistors, inductors, capacitors, and hybrid circuits, that reduce the amplitude of a signal without changing the waveform. The ATT-0290-01-SMA-02 is a type of attenuator specifically designed for use in telecommunications and other commercial applications. This article will discuss the field of application and working principle of the ATT-0290-01-SMA-02.

Application Field

The ATT-0290-01-SMA-02 is a broadband power attenuator. It is designed to attenuate RF signals in the frequency range of 0.5 MHz to 1 GHz. The attenuator has input and output ports with an impedance of 50 ohms and requires +/- 5V power supply. It also has an attenuation range of 30db and an insertion loss of 2.9 dB. The attenuator is typically used in applications such as testing and monitoring telecommunications signals and cellular systems.

The ATT-0290-01-SMA-02 is also used in the calibration of antenna systems, radar systems, base stations, and other RF devices. In addition, the attenuator is used to ensure that signals are within a certain range of minimum and maximum signal power levels.

The ATT-0290-01-SMA-02 has a wide operating temperature range of -40°C to 85°C, making it suitable for both indoor and outdoor applications. The attenuator is also designed to be highly reliable and can withstand up to 5,000 hours of continuous operation. It is also compliant with the MIL-STD-214B specification and is CE approved.

Working Principle

The ATT-0290-01-SMA-02 is a broadband attenuator that operates by using resistive elements to reduce the amplitude of a signal. It works by changing the resistance of the attenuator in response to a control signal.

The attenuator has two internal resistors that can be set to any value in the range of 0 ohms to 50 ohms. The two resistors work together to reduce the amplitude of the signal. The power supply is used to control the resistance of the attenuator. When the power supply is changed, the resistance of the resistors also change.

The attenuator also has an overload protection circuit. This circuit is designed to prevent excessive current from flowing through the attenuator and damaging it. If the current exceeds a certain limit, the circuit will cut off the power supply and protect the attenuator.

Conclusion

The ATT-0290-01-SMA-02 is a broadband power attenuator that is used in various RF applications such as testing and monitoring telecommunications signals, radar systems, base stations, and more. It is designed to have a wide operating temperature range and is highly reliable, making it suitable for both indoor and outdoor applications. The attenuator operates by using two internal resistors to reduce the amplitude of a signal in response to a control signal. It also has an overload protection circuit that is designed to protect it from excessive current damage.
