Attenuators

ATT-0290-11-SMA-02 is a kind of attenuator, it is usually applied in a transmission line. The main function of it is to reduce the power of an RF signal without distorting its waveform. This article is going to briefly introduce its application field and working principle.

Application Field

ATT-0290-11-SMA-02 is especially suitable for the applications where low cost and high performance in a small size are of great importance. It is also often applied to reduce high power and prevent the generated heat from affecting other components. Widely utilized in prototypes, prototypes evaluation and industrial production, this two-port device has the ability to minimize harmonics in transceivers and other Radio Frequency (RF) systems.

Working Principle

ATT-0290-11-SMA-02 consists of microstrip or stripline technology on a substrate using surface mounted components. An RF signal is coupled into the attenuator through a coaxial connector and is routed on its miniaturized substrate. Usually the substrate is FR-4 material, but other materials and thicknesses can also be used. The RF signal can be attenuated using different values. These values are determined by the amount of on-chip resistors, chip capacitors, and inductors. The signal can be routed using different topologies as well.

By changing the resistor values, the supplier can change the attenuation level. In some attenuators, a varying resistor can be used to adjust the level of signal attenuation. Also, the variable attenuator can be used to adjust the imbalance between the amplitude levels of the forward and reverse signals.

To sum it up, ATT-0290-11-SMA-02 is a miniaturized attenuator with applications in a variety of RF systems. It contains a substrate, surface-mounted components, and adjustable resistors and capacitors for attenuation levels. This device can help to maintain the transmission line with low cost and high performance, and it has the ability to minimize harmonics in radio frequency systems.
