Description

HMC425ALP3E are broadband 6-bit GaAs IC digital attenuators in low cost leadless surface mount packages. Covering 2.2 GHz to 8.0 GHz, the insertion loss is less than 4.5 dB typical. The attenuator bit values are 0.5 (LSB), 1, 2, 4, 8, and 16 dB for a total attenuation of 31.5 dB. Attenuation accuracy is excellent at ± 0.5 dB typical step error with an IIP3 of +40 dBm. Six control voltage inputs, toggled between 0 and +3 to +5V, are used to select each attenuation state. A single VDD bias of +3 to +5V is required.ApplicationsWLAN & Point-to-Multi-PointFiber Optics & Broadband TelecomMicrowave Radio & VSATMilitary
