The SKY12329-350LF is a monolithic GaAs, binary-weighted,5-bit, single positive control voltage digital attenuator which operates from 400 MHz–4 GHz. 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.
Please note: SKY12329-350LF is being discontinued and is not recommended for new designs.
