General Description
The HMC424A die is a broadband 6-bit GaAs IC digi-
tal attenuator MMIC chip. Covering DC to 13 GHz, the
insertion loss is less then 4 dB typical. The attenua-
tor 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
+42 dBm. Six control voltage inputs, toggled bet-
ween 0 and -5V, are used to select each attenuation
state. A single Vee bias of -5V allows operation at fre-
quencies down to DC.
Electrical Specifications, TA = +25° C, With Vee = -5V & VCTL = 0/-5V
