Description
AI
The HMC468ALP3E is a broadband 3-bit GaAs IC digital attenuators in a low cost leadless surface mount package. Covering DC to 6.0 GHz, the insertion loss is less than 1 dB typical up to 4 GHz. The attenuator bit values are 1 (LSB), 2 and 4 dB for a total attenuation of 7 dB. Attenuation accuracy is excellent at ±0.4 dB typical step error with an IIP3 of +55 dBm. Three control voltage inputs, toggled between 0 and +5V, are used to select each attenuation state. A single Vdd bias of +5V is required.APPLICATIONSCellular; UMTS/3G InfrastructureFixed Wireless & WLLMicrowave Radio & VSATTest Equipment
