TRX3 TRX4 TRX5 ANT TRX6 TRX7 TRX8 TX1 TX2 GPIO Interface V1 V2 V3 VDD V4 S2884 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 i...
