Functional Diagram

General Description

The HMC542BLP4E 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 1.7 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 +50 dBm.

Six bit serial control words are used to select each

attenuation state. A single Vcc bias of +5V is required.

Electrical Speciﬁcations, T_A= +25° C, with Vcc = +5V
