The PCAAL Series are chip attenuators that operate from DC to 18 GHz. They are available in attenuator configurations from 0 to 20 dB (0 to 10 dB, 12, 15 and 20 dB) and can handle up to 750 mW of average power. The PCAAL Series consist of a laser trimmed distributed thin film element on an alumina ceramic substrate with a protective paint layer and solderable leads. They have an attenuation accuracy of 0.5 dB to 1 dB and a VSWR of 1.35:1.
