The HMC290 is a broadband 2 - bit positive control GaAs IC digital attenuator in a 6 lead SOT26 surface mount plastic package. Covering 0.7 to 4 GHz the insertion loss is typically less than 0.7 dB. The attenuator bit values are 2 (LSB) and 4 dB for a total attenuation of 6 dB. Accuracy is excellent at 0.2 dB typical with an IIP3 of up to +52 dBm. Two bit control voltage inputs, toggled between 0 and +3 to +5 volts, are used to select each attenuation state at less than 50 uA each. A single Vdd bias of +3 to +5 volts applied through an external 5K resistor is required. The HMC290 is ideal for cellular, PCS, ISM, MMDS, and WLL handset & basestation applications. Occupying less than 9 mm, this is the smallest 2 - bit digital attenuator available.
