The attenuator has a least significant bit (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. This attenuator requires an external supply voltage of 2.7–5.5 V. The SKY12322-86LF is comprised of 5 fixed attenuators in cascade, each of which having a shunt bypass switch. Beginning at the LSB, which is 0.5 dB, each succeeding fixed attenuator produces twice the attenuation of the preceding stage. The state of each bypass s...
