The HMC288MS8 is a broadband 3-bit positive control GaAs IC digital attenuator in an 8 lead MSOP surface mount plastic package. Covering 0.7 to 3.7 GHz the insertion loss is typically less than 1.2 to 1.8 dB. The attenuator bit values are 2 (LSB), 4, and 8 for a total attenuation of 14 dB. Accuracy is excellent at 0.3 dB typical with an IIP3 of up to +51 dBm. Three bit control voltage inputs, toggled between 0 and +3 to +5V, are used to select each attenuation state at less than 50 uA each. A single Vdd bias of +3 to +5V applied through an external 5K r esistor is required. The HMC288MS8 is ideal for cellular, PCS, ISM, MMDS, and WLL applications while occupying less than 14.8 mm. |
