HMC603MS10 / 603MS10E v00.0905 0.5 dB LSB GaAs MMIC 5-BIT DIGITAL POSITIVE CONTROL ATTENUATOR, 0.7 - 3.8 GHz ATTENUATORS - SMT 5 Typical Applications Features The HMC603MS10 / HMC603MS10E is ideal for: 0.5 dB LSB Steps to 15.5 dB • Cellular/3G Infrastructure Single Positive Control Per Bit • ISM, MMDS ± 0.15 dB Typical Bit Error • WLAN, WiMAX, & WiBro High Input IP3: +50 dBm MSOP10 SMT Package Functional Diagram General Description The HMC603MS10 & HMC603MS10E are general purpose broadband 5-bit positive control GaAs IC digital attenuators in 10 lead MSOP surface mount plastic packages. Covering 0.7 to 3.8 GHz, the insertion loss is less than 2.0 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 with an IIP3 of +50 dBm. Five bit control voltage inputs, toggled between 0 and +3 to +5V, are used to select each attenuation state at less than 1.0 uA each. A single Vdd bias of +3 to +5V applied through an external 5K Ohm resistor is required.
