General Description

The HMC541LP3 & HMC541LP3E are broadband

1-bit GaAs IC digital attenuators in low cost lead-

less surface mount packages. This single posi-

tive control line digital attenuator utilizes off chip

AC ground capacitors for near DC operation,

making it suitable for a wide variety of RF and IF

applications. Covering DC to 5 GHz, the insertion

loss is less than 1 dB typical. Attenuation accuracy

is excellent at 0.2 dB typical step error. The attenu-

ator also features a high IIP3 of +50 dBm. One TTL/

CMOS control input is used to select the attenuation

state. A single Vdd bias of +5V is required.

Electrical Speciﬁcations,

T_A= +25° C, With Vdd = +5V & Vctl = 0/+5V (Unless Otherwise Noted)
