1.0 to 6.0 GHz SPDT Switch

The SKY13585-679LF is a single-pole, double-throw (SPDT) switch intended for mode switching in WLAN applications. Using advanced switching technologies, the SKY13585-679LF maintains low insertion loss and high isolation for all switching paths.

The high-linearity performance and low insertion loss achieved by the switch make it an ideal choice for low-power transmit/receive applications. Depending on the logic voltage applied to the control pin (VCTL), the INPUT pin is connected to one of the two switched RF outputs (OUTPUT1 or OUTPUT2) using a low insertion loss path, while the path between the INPUT pin and the other OUTPUT pin is in a high-isolation state. The switch is "reflective short" on the isolated port.

The SKY13585-679LF has integrated DC blocking capacitors, so no external DC blocking capacitors are required.

The switch is manufactured in a compact, 1 × 1 × 0.32 mm, 6-pin exposed pad plastic Micro Lead-frame Package Dual (MLPD) package.
