The HMC290(E) is a broadband 2-bit positive control GaAs IC digital attenuators 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 Ohm resistor is required. Occupying less than 9 mm², this is the smallest 2 - bit digital attenuator available.ApplicationsCellularPCS, ISM, MMDSWLL Handset & BaseStation
