HMC470LP3 / 470LP3E v04.1108 1 dB LSB GaAs MMIC 5-BIT DIGITAL POSITIVE CONTROL ATTENUATOR, DC - 3 GHz 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 TE 16 Lead 3x3mm SMT Package: 9mm2 Included in the HMC-DK004 Designer's Kit Functional Diagram General Description LE The HMC470LP3(E) is a broadband 5-bit GaAs IC digital attenuators in low cost leadless surface mount 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.
