General Discription

The HMC539LP3 & HMC539LP3E are broadband

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

less surface mount packages. This single positive

control line per bit digital attenuator utilizes an off

chip AC ground capacitor for near DC operation,

making it suitable for a wide variety of RF and IF

applications. Covering DC to 4 GHz, the insertion loss

is less than 0.7 dB typical. The attenuator bit values

are 0.25 (LSB), 0.5, 1, 2, and 4 dB for a total attenu-

ation of 7.75 dB. Attenuation accuracy is excellent

at 0.05 dB typical step error. The attenuator also

features a high IIP3 of +50 dBm. Five TTL/CMOS

control inputs are used to select each attenuation

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