0.7 to 3.0 GHz DP21T (SP12T/SP9T) MIPI Main Antenna Switch for Carrier Aggregation

The SKY13535 is an SP12T and SP9T with MIPI control antenna switch that is LTE-A Release 10 and Release 11 compliant. Using advance switching technologies, the SKY13535 maintains low insertion loss and high isolation for both transmit and receive switching paths. The high linearity performance and low insertion loss achieved by the SKY13535 makes it an ideal choice for carrier aggregation applications.

The SP12T and SP9T can accommodate UMTS/C2K/Edge/GSM/ LTE applications as well as intraband carrier aggregation. There is an integrated filter in the low band side of the switch allowing all of the low band TRX ports to be used for B17. The switch also exhibits an excellent 2nd/3rd order intermodulation distortion performance.

The SKY13535 is packaged in a small 3.6 x 2.8 x 1.0 mm 28-lead surface mount package. Switching is controlled by an integrated Mobil Industry Processor Interface (MIPI) decoder. There are separate control registers for controlling low band and high band independently. No external DC blocking capacitors are required on the RF paths as long as no DC voltage is applied.. The switch can operate over the temperature range of -30°C to +90°C.
