The HMC290 & HMC290E are broadband 2 - bit positive control GaAs IC digital attenuators in 6 lead SOT26 surface mount plastic packages. Covering 0.7 to 4 GHz, the insertion loss is typically less than 0.7 dB. The HMC290 & HMC290E 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 Ohm resistor is required. Occupying less than 9 mm2, this is the small-est 2 - bit digital attenuator available.
