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.
