SKY13456-11

0.6 to 2.7 GHz DP14T Switch with MIPI® RFFE Interface

Please note: SKY13456-11 is being discontinued and is not recommended for new designs. The suggested replacement is SKY13533-11

The SKY13456 is a Double-Pole, Fourteen-Throw (DP14T) antenna switch. The device maintains low insertion loss and high isolation for both transmit and receive switching paths. The high linearity performance and low insertion loss makes the SKY13456 an ideal choice for carrier aggregation applications.

The device contains two Single-Pole, Seven-Throw (SP7T) switches that can accommodate UMTS, CDMA2000, EDGE, GSM, and LTE applications. 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.

The high and low band SP7T switch bank can be independently controlled with two separate registers. Register 0 controls the high bands (pin signals TRX1 to TRX6) and Register 1 controls the low bands (pin signals TRX7 to TRX12). No external DC blocking capacitors are required on the RF path as long as no DC voltage is applied. There is an integrated B17 3rd Harmonic filter on the TRx10 port.

The switch also provides an excellent triple beat ratio and 2nd/3rd Order Intermodulation Distortion (IMD2/IMD3) performance.

The SKY13456 is manufactured in a small, 2.8 x 3.2 mm, 26-pin Multi-Chip Module (MCM) package.
