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.
