The attenuator has a least significant bit (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. This attenuator requires an external supply voltage of 2.7–5.5 V The SKY12323-303LF is comprised of five fixed attenuators in cascade, each of which having a shunt bypass switch. Beginning at the LSB, which is 1 dB, each succeeding fixed attenuator produces twice the attenuation of the preceding stage. The sta...
