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 4.0 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
attenuation of 7.75 dB. Attenuation accuracy is excel-
lent 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.
