Attenuators, one of the most important components in radiofrequency (RF) and microwave systems, are used to control the amplitude of the signal propagating in a transmission line. In particular, attenuators are used to control the transmitted power of a transmitter or to adjust the received signal level of a receiver.

One such attenuator is the ATT-290F-30-SMA-02. This model of attenuator is a surface mount type and is designed for use in dielectric substrate technology. It is a four-bit voltage controlled attenuator with 30 dB of attenuation and a maximum frequency handling of 3 GHz. The attenuator is rated for 0.5 watts of power dissipation and operates from -40°C to 85°C.

Application Field: The ATT-290F-30-SMA-02 attenuator is suitable for use in a variety of applications, including cellular base station circuitry, medical instrumentation, satellite communications, and wireless communications. The attenuator is particularly useful for reducing RF signals to the levels required by sensitive RF receivers.

Working Principle: This model of attenuator works as an electronic variable resistor, with both a logarithmic and linear response to signal power. The attenuator is adjustable over a range of 30 dB in 1dB steps. The device works by absorbing some of the RF signal as it passes through the attenuator, effectively reducing the overall power of the signal. This attenuation is controlled by voltage input signals, with a 1volt signal representing 1dB attenuation. This allows for precise adjustment of the signal level being sent or received.

The ATT-290F-30-SMA-02 attenuator boasts excellent return loss and repeatability, making it suitable for high speed, low noise applications. It also has a low insertion loss and low temperature coefficient, thus ensuring its stability and accuracy in operation. As such, it offers excellent performance and reliability for users.
