Skyworks射频芯片SKY13582-676LF

No external DC blocking capacitors are required on the RF paths

as long as there is no DC voltage on the RF line. The switch can

operate over the temperature range of −40 C to +85 C.

Switching is controlled by two CMOS/TTL compatible control

voltage inputs (VC1 and VC2). Depending on the logic voltage level

applied to the control pin, the RFC pin is connected to one of three

switched RF outputs (RF1, RF2, or RF3) by using a low insertion

loss path, while the path between the RFC pin and the other RF

pins is in isolation.

The SKY13582-676LF is provided in a small 9-pin,

1.1  1.1  0.5 mm QFN package.

A functional block diagram is shown in Figure 1.
