HMC273AMS10GE v06.0218 1 dB LSB GaAs MMIC 5-BIT DIGITAL ATTENUATOR, 0.7 - 3.8 GHz Typical Applications Features The HMC273AMS10G(E) is ideal for: RoHs Compliant Product Cellular UMTS/3G Infrastructure 1 dB LSB Steps to 31 dB ISM, MMDS, WLAN, WiMAX Single Positive Control Per BIT Microwave Radio & VSAT 0.2 dB Typical Bit Error 2 Test Equipment and Sensors Miniature MSOP 10 Package: 14.8mm Included in the HMC-DK004 Designers Kit Functional Diagram General Description The HMC273AMS10G(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 3 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 +46 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 bias of +3 to +5 volts applied through an external 5K Ohm resistor is required. Electrical Specifications, T = +25 C, Vdd = +3V to +5V & Vctl = 0/Vdd (Unless Otherwise Stated) A Parameter Frequency Min. Typical Max.
