Product Details

The HMC939ALP4E is a 5-bit digital attenuator with a 31 dB attenuation control range in 1 dB steps.

The HMC939ALP4E offers optimum insertion loss, attenuation accuracy, and input linearity over the specified frequency range from 100 MHz to 33 GHz.

The HMC939ALP4E requires dual supply voltages, VDD = +5 V and VSS = −5 V, and provides CMOS-/TTL-compatible parallel control interface by incorporating an on-chip driver.

The HMC939ALP4E comes in a RoHS compliant, compact, 4 mm × 4 mm LFCSP package. See HMC939A-DIE for the die version of HMC939ALP4E.

Applications

  • Test instrumentation
  • Microwave radios and very small aperture terminals (VSATs)
  • Military radios, radars, electronic counter measures (ECMs)
  • Broadband telecommunications systems
