Functional Description
The SKY13523-639LF includes an internal decoder and internal
blocking capacitors on the RF common ports. External DC
blocking capacitors are required on the RF1, RF2, and RF3 ports
for proper operation. DC decoupling capacitors may be added on
the VDD and control lines if necessary.
Switching is controlled by two control voltage inputs, V1 and V2.
Depending on the logic voltage level applied to the control pins,
the antenna pin is connected to one of three switched RF outputs.
Electrical and Mechanical Specifications
The absolute maximum ratings of the SKY13523-639LF are
provided in Table 2. Electrical specifications are provided in
Table 3.
The state of the SKY13523-639LF is determined by the logic
shown in Table 4.
