Description
The SKY13453-385LF is a single-pole, double-throw (SPDT)
switch intended for mode switching in pre-power amplifier (PA)
cellular or WLAN applications. Using advanced switching
technologies, the SKY13453-385LF 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 mode switching before the
PA in cellular 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. The pin configuration and package are shown in
Figure 2. Signal pin assignments and functional pin descriptions
are provided in Table 1.
