Description
The SKY12339 - 350LF is a monolithic, GaAs binary - weighted five -
bit single positive control voltage digital attenuator. The device
operates from 0.4 to 3.0 GHz. DC power consumption is very low,
t ypically 1.5 mA, with a supply voltage of 5 V.
The SKY12339 - 350LF 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 4.5 to 5.5 V is
required.
The SKY12339 - 350LF is comprised of five cascaded fixed
attenuators, each of which has a shunt bypass switch. Beginning
at the 1 dB LSB, each succeeding fixed attenuator produces 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, which bypasses that
fixed attenuator stage; a logic low opens the switch to force the
input signal to that stage through the associated attenuator.
A functional block diagram is shown in Figure 1. The pin
configuration and package are shown in Figure 2. Signal pin
assignments and functional pin descriptions are provided in
Table 1.
