The HMC603 devices are general-purpose broadband, 5-bit positive control, GaAs, IC digital attenuators available in a 10-lead MSOP or 16-lead QSOP surface-mount (SMT) plastic package. Covering 0.7 GHz to 3.8 GHz, the insertion loss is less than 1.9 dB or 2 dB typical. The attenuator bit values are 0.5 (LSB), 1, 2, 4, and 8 dB for a total attenuation of 15.5 dB. Attenuation accuracy is excellent at ±0.15 dB typical step error with an IIP3 of +50 dBm. Five-bit control voltage inputs, toggled between 0 V and +3 V to +5 V, are used to select each attenuation state at less than 1 μA each. A single VDD bias of +3 V to + 5 V applied through an external 5 kΩ resistor is required. Applications Cellular/3G infrastructure ISM, MMDS WLAN, WiMAX, and WiBro
