The HMC542ALP4(E) is a broadband 6-bit GaAs IC
digital attenuator with a CMOS compatible serial
to parallel driver in low cost leadless surface mount
package. This serial control digital attenuator incorp
rates off chip AC ground capacitors for near DC opera-
tion, making it suitable for a wide variety of RF and
IF applications. Covering DC to 4 GHz, the inser-
tion loss is 1.5 dB and the attenuator bit values are
0.5 (LSB), 1, 2, 4, 8, and 16 dB for a total attenua-
tion of 31.5 dB. Attenuation accuracy is excellent at
?.25 dB typical step error with an IIP3 of +45 dBm.
Six bit serial control words are used to select each
attenuation state. A single Vdd bias of +5V is required.
