PRELIMINARY DATA SHEET
SKY13441: 0.4-2.7 GHz SP10T Switch with GPIO Interface
• 2G/3G multimode cellular handsets (UMTS, CDMA2000, EDGE,
• Embedded data cards
• Broadband frequency range: 0.4 to 2.7 GHz
• Single, positive DC power supply (2.5 to 3.3 V)
• Excellent Band 13 2nd harmonic rejection
• Integrated, low-pass harmonic filter for GSM transmit paths
• Integrated GPIO interface
• Any of eight TRX ports can be used for WCDMA transmit/receive
or GSM receive functions
• Small MCM (20-pin, 3.2 x 2.5 mm) package (MSL3, 260 °C per
The SKY13441 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 SKY13441 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. SKY13441 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 SKY13441 is manufactured in a compact,
3.2 x 2.5 mm, 20-pin Multi-Chip Module (MCM) 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
