Description

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. A functional block diagram is shown

in Figure 1.
