The SKYA21024 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 SKYA21024 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.
