Functional Diagram

General Description

The HMC425 die is a broadband 6-bit GaAs IC

digital attenuator MMIC chip. Covering 2.4 to 8.0

GHz, the insertion loss is less then 3.5 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 +40 dBm. Six con-

trol voltage inputs, toggled between 0 and +3 to

+5V, are used to select each attenuation state. A

single Vdd bias of +3 to +5V is required.

Electrical Speciﬁcations,

T_A= +25° C, With Vdd = +5V & Vctl = 0/+5V (Unless Otherwise Noted)
