5 to 1800 MHz Single Control SPDT

Please note: SKY13548-385LF is being discontinued and is not recommended for new designs.

The SKY13548-385LF is a single-pole, double-throw (SPDT) 75 Ω switch intended for mode switching in either pre-select filter or post-select filter in STB and cable modem applications. Using advanced switching technologies, the SKY13548-385LF 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 cable modem and STB applications. Depending on the logic voltage applied to the control pin (VCTL), the RFC pin is connected to one of the two switched RF outputs, RF1 or RF2, using a low insertion loss path, while the path between the RFC pin and the other RF path is in a high isolation state.

The switch is manufactured in a compact, 1 x 1 mm, 6-pin Quad Flat No-Lead (QFN) package.
