The HMC470LP3(E) is a broadband 5-bit GaAs IC digital attenuator in low cost lead-less surface mount package. 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.

Applications

  • Cellular; UMTS/3G Infrastructure 
  • ISM, MMDS, WLAN, WiMAX 
  • Microwave Radio & VSAT 
  • Test Equipment and Sensors
