HMC470LP3 / 470LP3E v04.1108 1 dB LSB GaAs MMIC 5-BIT DIGITAL POSITIVE CONTROL ATTENUATOR, DC - 3 GHz 5 Typical Applications Features The HMC470LP3(E) is ideal for: 1 dB LSB Steps to 31 dB Cellular UMTS/3G Infrastructure Single Control Line Per Bit ISM, MMDS, WLAN, WiMAX TTL/CMOS Compatible Control Microwave Radio & VSAT 0.3 dB Typical Step Error Test Equipment and Sensors Single +5V Supply 16 Lead 3x3mm SMT Package: 9mm2 Included in the HMC-DK004 Designers Kit Functional Diagram General Description The HMC470LP3(E) is a broadband 5-bit GaAs IC digital attenuators in low cost leadless surface mo- unt packages. This single positive control line per bit digital attenuator incorporates off chip AC ground capacitors for near DC operation, making it suitable for a wide variety of RF and IF applications. Covering DC to 3 GHz, the insertion loss is less than 1.5 dB typical. The attenuator bit values are 1 (LSB), 2, 4, 8, and 16 dB for a total attenuation of 31 dB. Attenuation accuracy is excellent at 0.3 dB typical step error with an IIP3 of +45 dBm. Five TTL/CMOS control inputs are used to select each attenuation state. A single Vdd bias of +5V is required.
