Functional Diagram
Electrical Specifications, T
A = +25° C, with Vcc = +5V
the HMC542ALP4(e) is ideal for:
Cellular/PCs/3G Infrastructure
IsM, MMDs, WLAn, WiMAX, & WiBro
Microwave radio & VsAt
test equipment and sensors
0.5 dB LsB steps to 31.5 dB
ttL/CMos Compatible serial Data Interface
sPI Compatible serial output

single +5V supply
24 Lead 4x4mm QFn Package: 16mm
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
±0.25 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.
