Description
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.
The SKY12329-350LF is comprised of 5 fixed attenuators in
cascade, each of which having a shunt bypass switch. Beginning
at the LSB, which is 1 dB, each succeeding fixed attenuator pro-
duces twice the attenuation of the preceding stage. The state of
each bypass switch is controlled by the logic level voltage applied
to the associated control voltage input; a logic high voltage closes
the associated switch, thereby

bypassing that fixed attenuator stage, and a logic low opens the
switch to force the input signal to that stage through the associ-
ated attenuator.
DC power consumption is very low, 100 µA maximum with con-
trol voltage and supply voltage of 5 V. The switch can operate
over the temperature range of -40 °C to +85 °C.
An evaluation board is available upon request.
