General Description
The HMC468LP3 is a broadband 3-bit GaAs IC digital attenuator 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 +50 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.
Electrical Specifications, TA = +25° C, With Vdd = +5V & Vctl = 0/+5V
