High Power Fixed Attenuator

In some module or RF system, attenuator can decrease output power without disturbing or transforming of signal waveform or data when the output power is too high and could damage the system or equipment. Not only can attenuator improve the Impedance matching and secure the reliability of circuit, but attenuator can also be used to adapt the level between the two different circuits or devices. Psatek supply fixed attenuators operating from 1W to 500W, the frequency range is from DC to 67GHz, and with various connectors to select. Please contact the sales team (sales@psatek.com) for a quote.
