Description

The HMC542LP4 & HMC542LP4E are broadband 6-bit GaAs IC digital attenuators with CMOS compatible serial to parallel drivers in low cost leadless surface mount packages. This serial control digital attenuator HMC542LP4 & HMC542LP4E 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 3.0 GHz, the insertion loss is less than 1.5 dB typical. The attenuator bit values are 0.5 (LSB), 1, 2, 4, 8, and 16 dB for a total attenuation of 31.5 dB. Attenuation accuracy is excellent at ± 0.25 dB typical step error with an IIP3 of +45 dBm. Six bit serial control words of HMC542LP4 & HMC542LP4E are used to select each attenuation state. A single Vdd bias of +5V is required.
