HMC603MS10 603MS10E / v00.0905 0.5 dB LSB GaAs MMIC 5-BIT DIGITAL POSITIVE CONTROL ATTENUATOR, 0.7 - 3.8 GHz 5 Typical Applications Features The HMC603MS10 / HMC603MS10E is ideal for: 0.5 dB LSB Steps to 15.5 dB T M (cid:129) Cellular/3G Infrastructure Single Positive Control Per Bit S (cid:129) ISM, MMDS ± 0.15 dB Typical Bit Error - (cid:129) WLAN, WiMAX, & WiBro High Input IP3: +50 dBm S MSOP10 SMT Package R O T Functional Diagram General Description A U The HMC603MS10 & HMC603MS10E are general N purpose broadband 5-bit positive control GaAs IC E digital attenuators in 10 lead MSOP surface mount T plastic packages. Covering 0.7 to 3.8 GHz, the inser- T tion loss is less than 2.0 dB typical. The attenuator A 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.
