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.
