The SKY13353-337LF is a GaAs pHEMT Double-Pole, Double- Throw (DPDT) switch designed for 0.5 to 3.0 GHz diversity WLAN applications that use two antennas for both transmit and receive paths. The device provides high linearity, low insertion loss, and high isolation. Switching is controlled by four control voltage inputs (CTRL1, CTRL2, CTRL3, and CTRL4). Depending on the logic voltage level applied to the control pins, the four RF ports (RF1, RF2, RF3, and RF4) are connected together using a low insertion loss path, while maintaining a high isolation path to the alternate ports. Series DC blocking capacitors are required on all RF ports for proper operation. The SKY13353-337LF is provided in a 3 x 3 mm, 12-pin Quad Flat No-Lead (QFN) package.
