HMC335

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 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 Vee bias of -5V allows operation down to DC.
