Working Principle

The Att-290M-04-SMA-02 attenuator consists of a ceramic substrate with four resistive elements on the top surface. The four resistors are connected in parallel in a pi-network configuration. The ceramic substrate provides a high thermal stability as well as a low output characheteristic impedance. The four resistors are matched to maintain a flat frequency response and provide a consistent level of signal attenuation at frequencies up to 1GHz.The resistive components of the Att-290M-04-SMA-02 attenuator are connected in such a way that the power loss reduces as the input signal level decreases. As a result, the attenuator provides a balanced attenuation, regardless of the signal level, and is particularly well suited for decreasing signal levels to reduce noise and improve performance in a variety of applications.
