HMC472ALP4E, RF ATTENUATOR, 3.8GHZ, 5.5V, HQFN-24
The HMC472ALP4E is a broadband 6-bit GaAs MMIC Digital Positive Control Attenuator which operates between DC and 3.8GHz.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. The attenuator bit values are 0.5 (LSB), 1, 2, 4, 8 and 16dB for a total attenuation of 31.5dB. Attenuation accuracy is excellent at ±0.25dB typical step error with an IIP3 of +54dBm. Six TTL/CMOS control inputs are used to select each attenuation state. A single Vdd bias of +5V is required.
• 0.5dB LSB steps to 31.5dB
