HMC425LP3 0.5 dB LSB 6-Bit Digital Attenuator SMT, 2.2 - 8.0 GHz
The HMC425LP3(E) is a broadband 6-bit GaAs IC digital attenuator in a low cost leadless surface mount package. Covering 2.2 to 8.0 GHz, the insertion loss is less then 3.8 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.
