Functional Diagram

General Description

The HMC424 die is a broadband 6-bit GaAs IC

digital attenuator MMIC chip. Covering DC to 13

GHz, the insertion loss is less then 4 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 typi-

cal step error with an IIP3 of +32 dBm. Six con-

trol voltage inputs, toggled between 0 and -5V,

are used to select each attenuation state. A single

Vee bias of -5V allows operation at frequencies

down to DC.

Electrical Speciﬁcations, T_A= +25° C, With Vee = -5V & VCTL = 0/-5V
