The QAT-X+ series of surface-mount fixed attenuators cover the wide frequency range of DC to 50 GHz with nominal fixed attenuation values of 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 15, 20, and 30 dB. The absorptive 50 ohm attenuators are fabricated with a GaAs MMIC Integrated Passive Device (IPD) process that achieves excellent attenuation accuracy with frequency. As an example, the 10 dB model QAT-10+ attenuator has typical accuracy of 10.1 dB through 5 GHz, 10.2 dB through 20 GHz, and 10.3 dB through 50 GHz. The attenuators handle as much as 2W input power for the lowest attenuation values and as much as 0.8W power for the 30 dB model QAT-30+. The RoHS-compliant attenuators are supplied in a 2x2mm MCLP(™) package and have an operating temperature range of -55 to +105ºC.
