Description
The SKYA21054 is a single-pole, eight-throw (SP8T) antenna
switch with an integrated Mobile Industry Processor Interface
(MIPI) controller. Using an advanced switching technology, the
SKYA21054 maintains low insertion loss and high isolation, which
makes it an ideal choice for UMTS, CDMA2000, EDGE, GSM, and
LTE applications.
The design features eight linear TRX ports. The switch has an
excellent triple beat ratio and second/third order intermodulation
distortion (IMD2/IMD3) performance.
Switching is controlled by the MIPI decoder. There is an external
MIPI select pin that enables how the switch responds to power
mode triggers. When this pin is grounded, the switch responds to
any of the power mode triggers. When this pin is left open, the
switch responds to individual power mode triggers. No external
DC blocking capacitors are required on the RF paths as long as no
DC voltage is applied.
The SKYA21054 is manufactured in a compact,
2.5 x 2.5 x 0.75 mm, 20-pin surface-mount 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.
