General Description
The HMC335G16 is a broadband 5-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 2.3 dB typical. The attenu-
ator bit values are 1 (LSB), 2, 4, 8, and 16 dB for a
total attenuation of 31 dB. Attenuation accuracy is
excellent at ±0.5 dB typical with an IIP3 of up to +44
dBm. Five bit control voltage inputs, toggled between
0 and -5V, are used to select each attenuation state at
less than 70 µA each. A single Vee bias of -5V allows
operation down to DC.
