General Description
The HMC539ALP3/539ALP3E is a broadband
5-bit GaAs IC digital attenuator in a low cost lead-
less surface mount package. 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 inser-
tion 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
excellent at ± 0.05 dB typical step error. The attenu-
ator also features a high IIP3 of +62 dBm. Five TTL/
CMOS control inputs are used to select each attenua-
tion state. A single Vdd bias of +3V to +5V is required.
