SKY12328-350LF 0.5-4.0 GHz Five-Bit Digital Attenuator (0.5 dB LSB)

The SKY12328-350LF is a monolithic, GaAs binary-weighted five-bit single positive control voltage digital attenuator. The device operates from 0.5 to 4.0 GHz. DC power consumption is very low, typically 100 μA maximum, with a control and supply voltage of 5.5 V. The SKY12328-350LF has an LSB of 0.5 dB and total attenuation of 15.5 dB. The two RF ports are bilateral; each can be used as the RF input or the RF output. An external supply voltage of 2.7 to 5.5 V is required.
