SKY12323-303LF 0.5-3.0 GHz Five-Bit Digital Attenuator (1 dB LSB)
The SKY12323-303LF is a monolithic, GaAs binary-weighted five-bit single positive control voltage digital attenuator. The device operates from 0.5 to 3.0 GHz. DC power consumption is very low, typically 100 μA maximum, with a control and supply voltage of 3 V. The SKY12323-303LF has an LSB of 1 dB and total attenuation of 31 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.
