Functional Diagram

General Description

The HMC424G16 is a broadband 6-bit GaAs IC

digital attenuator in a 16 lead glass/metal (hermetic)

surface mount package. Covering DC to 3 GHz, the

insertion loss is less than 3 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 typical step error with an IIP3

of +32 dBm. Six control voltage inputs, toggled bet-

ween 0 and -5V, are used to select each attenuation

state at less than 70 μA each. 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
