16 Lead Hermetic SMT Package
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.
