HMC273MS10G / 273MS10GE v04.0907 1 dB LSB GaAs MMIC 5-BIT DIGITAL ATTENUATOR, 0.7 - 3.8 GHz 5 ATTENUATORS - SMT Typical Applications The HMC273MS10G(E) is ideal for: • Cellular; UMTS/3G Infrastructure • ISM, MMDS, WLAN, WiMAX • Microwave Radio & VSAT • Test Equipment and Sensors Features RoHs Compliant Product 1 dB LSB Steps to 31 dB Single Positive Control Per BIT ±0.2 dB Typical Bit Error Miniature MSOP 10 Package: 14.8mm2 Included in the HMC-DK004 Designer’s Kit Functional Diagram General Description The HMC273MS10G(E) is a general purpose broadband 5-Bit positive control GaAs IC digital attenuator in a 10 lead MSOP plastic package. 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 of 31 dB. Accuracy is excellent at ±0.2 dB typical with an IIP3 of up to +48 dBm. Five bit control voltage inputs, toggled between 0 and +3 to +5 volts, are used to select each attenuation state. A single Vdd bias of +3 to +5 volts applied through an external 5K Ohm resistor is required.
