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.
