HMC542ALP4 0.5dB LSB 6-Bit Digital Attenuator SMT, DC - 4 GHz
The HMC542ALP4(E) is a broadband 6-bit GaAs IC digital attenuator with CMOS compatible serial to parallel drivers in a low cost leadless surface mount package. This serial control digital attenuator incorporates off chip AC ground capacitors 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 1.5 dB typical. The attenuator bit values are 0.5 (LSB), 1, 2, 4, 8, and 16 dB for a total attenuation of 31.5 dB. Attenuation accuracy is excellent at ± 0.25 dB typical step error with an IIP3 of +45 dBm. Six bit serial control words are used to select each attenuation state. A single Vdd bias of +5V is required.
