SKY13477-001A

3P4T Transmit/Receive LTE Switch in a WLCSP Package


The SKY13477-001A is a Three-Pole, Four-Throw (3P4T) switch. Switching is controlled by an integrated GPIO interface with four control pins. Depending on the logic voltage level applied to the control pins, the following switched outputs are possible:

  • RF1 port can be connected to the RF6 or RF5 port.
  • RF2 port can be connected to the RF7 port.
  • RF3 port can be connected to the RF4, RF5, RF6, or RF7 port.


No external DC blocking capacitors are required as long as no DC voltage is applied on any RF path. The internal voltage regulator allows the VDD supply value to be within 2.45 V to 3.00 V. Logic control is 1.8 V nominal.

The SKY13477-001A is provided in a compact 15-bump, 1.942 x 1.142 x 0.420 mm (maximum) Wafer Level Chip Scale Package (WLCSP) that meets requirements for board-level assembly. Bump and Under-Bump Metallization (UBM) diameters are 200 microns.
