Dual-Band Matched SP4T WiFi Switch

The SKY13575-639LF is a dual-band single-pole, four-throw switch with an integrated 50 Ω match on all RF output ports. External DC blocking capacitors are required on the RF paths. The switch can operate over the temperature range of -40 °C to 90 °C.

Switching is controlled by two CMOS/TTL compatible control voltage inputs: VC1 and VC2. Depending upon the logic voltage level applied to the control pins, the RFC pin is connected to one of four switched RF outputs (RF1 to RF4) by a low insertion loss path, while the path between the RFC pin and the other RF pins is in isolation. The isolated ports are terminated to a 50 Ω load.

The SKY13575-639LF is packaged in a small, 14-pin, 1.6 x 1.6 x 0.45 mm QFN package.

Features

  • Off ports matched to 50 Ω

  • High isolation: 40 dB at 2.5 GHz, 30 dB at 6 GHz (typical)
  • Integrated GPIO interface
  • Small QFN (14-pin, 1.6 x 1.6 x 0.45 mm) package (MSL1, 260 °C per JEDEC J-STD-020)
