General Discription

The HMC540LP3 & HMC540LP3E are broadband

4-bit GaAs IC digital attenuators in low cost leadless

surface mount packages. This single positive control

line per bit 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 5.5 GHz, the insertion loss is less than 1.0 dB typical.

The attenuator bit values are 1 (LSB), 2, 4 and 8 dB for

a total attenuation of 15 dB. Attenuation accuracy is

excellent at 0.2 dB typical step error. The attenuator

also features a IIP3 of +50 dBm. Four TTL/CMOS

control inputs are used to select each attenuation

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