Overview of HMC539ALP3
The HMC539ALP3/539ALP3E is a broadband5-bit GaAs IC digital attenuator in a low cost leadless surface mount package. This single positive control line per bit digital attenuator utilizes an offchip AC ground capacitor for near DC operation,making it suitable for a wide variety of RF and IFapplications. Covering DC to 4 GHz, the insertion loss is less than 0.7 dB typical. The attenuatorbit values are 0.25 (LSB), 0.5, 1, 2, and 4 dB for atotal attenuation of 7.75 dB. Attenuation accuracy isexcellent 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 attenuation state. A single Vdd bias of +3V to +5V is required.
