Functional Diagram
General Description
The HMC941 die is a broadband 5-bit GaAs IC digi-
tal attenuator MMIC chip. Covering 0.1 to 30 GHz, the
insertion loss is less than 4 dB typical. The attenuator
bit values are 0.5 (LSB), 1, 2, 4, 8, for a total attenu-
ation of 15.5 dB. Attenuation accuracy is excellent
at less than ± 0.5 dB typical step error with an IIP3 of
+45 dBm. Five control voltage inputs, toggled between
+5V and 0V, are used to select each attenuation state.
Electrical Specifications, TA = +25° C, With Vdd = +5V, Vss = -5V & VCTL = 0/ +5V
