Product Overview

HMC346ALC3B is an absorptive voltage variable attenuator (VVA). It features an on-chip reference attenuator for use with an external op-amp to provide simple single voltage attenuation control, 0 to -5V. This device is ideal in designs where an analogue DC control signal must control RF signal levels over a 30dB amplitude range. It allows the use of surface mount manufacturing techniques. It is widely used in application such as test instrumentation, fibre optics & broadband telecom, microwave radio & VSAT, military radios, radar, & ECM etc.
  • Wide bandwidth: DC - 18GHz
  • Low phase shift vs attenuation
  • Simplified voltage control
  • Attenuation range is 30dB typical at (TA = +25°C)
  • Return loss is 10dB typical at (TA = +25°C)
  • Input third order intercept is +30dBm typical at (TA = +25°C)
  • Switching characteristics is 8ns typical at (TA = +25°C)
  • Operating temperature is -40°C to +85°C
  • Package style is terminal ceramic leadless chip carrier (LCC-12)
