Description
The SKY13442-553LF is a Single Pole, Ten-Throw (SP10T)
antenna switch with an integrated General Purpose Input/Output
(GPIO) interface and dual low-pass harmonic filters. The switch
has eight transmit/receive ports, any of which can be used for
WCDMA transmit/receive or GSM receive functions.
Using advance switching technologies, the SKY13442-553LF
maintains low insertion loss and high isolation for both transmit
and receive switching paths. The switch also exhibits an excellent
triple beat ratio and 2nd/3rd order modulation distortion
performance.

Figure 1. SKY13442-553LF Block Diagram
Switching is controlled by an integrated GPIO interface.
Depending on the logic applied to the decoder, the antenna pin is
connected to one of ten switched RF ports using a low insertion
loss path, while the paths between the antenna pin and the other
RF pins are in a high isolation state. No external DC blocking
capacitors are required on the RF paths.
The SKY13442-553LF is manufactured in a compact,
2.5 x 2.5 mm, 20-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.
