General Description
The HMC335G16 is a broadband 5-bit GaAs IC
digital attenuator in a 16 lead glass/metal (hermetic)
surface mount package. Cov ering DC to 3 GHz, the
insertion loss is less than 2.3 dB typical. The attenuator 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 V ee bias
of -5V allows operation down to DC.
