HMC273MS10G 273MS10GE / v04.0907 1 dB LSB GaAs MMIC 5-BIT DIGITAL ATTENUATOR, 0.7 - 3.8 GHz 5 Typical Applications Features The HMC273MS10G(E) is ideal for: RoHs Compliant Product T M (cid:129) Cellular; UMTS/3G Infrastructure 1 dB LSB Steps to 31 dB S (cid:129) ISM, MMDS, WLAN, WiMAX Single Positive Control Per BIT E - (cid:129) Microwave Radio & VSAT ±0.2 dB Typical Bit Error S (cid:129) Test Equipment and Sensors Miniature MSOP 10 Package: 14.8mm2 R T O Included in the HMC-DK004 Designer’s Kit T A Functional Diagram General Description U E N The HMC273MS10G(E) is a general purpose E broadband 5-Bit positive control GaAs IC digital T attenuator in a 10 lead MSOP plastic package. T L A Covering 0.7 to 3.8 GHz, the insertion loss is typically less than 2.5 dB. The attenuator bit values are 1 (LSB), 2, 4, 8, and 16 dB for a total attenuation O of 31 dB. Accuracy is excellent at ±0.2 dB typical with an IIP3 of up to +48 dBm. Five bit control vol- tage inputs, toggled between 0 and +3 to +5 volts, are used to select each attenuation state. A single Vdd S bias of +3 to +5 volts applied through an external 5K Ohm resistor is required.
