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
