SKY13408-465LF Block Diagram Description Skyworks Green products are compliant with all applicable legislation and are halogen-free. The SKY13408-465LF is a GaAs pHEMT single-pole, triple-throw For additional information, refer to Skyworks (SP3T) high power switch with 50 terminated outputs. The high Denition of Green, document number linearity performance and low insertion loss achieved by the SQ04-0074. SKY13408-465LF make it an ideal choice for 802.11a/c, WiMAX, and higher power WLAN applications such as access points. The switch is manufactured in a compact, 2 x 2 mm, 12-pin Quad Flat No-Lead (QFN) package. A functional block diagram is shown in Figure 1. The pin 12 11 10 configuration and package are shown in Figure 2. Signal pin assignments and functional pin descriptions are provided in V3 1 9 V1 Table 1.

The value of the capacitors determines the low frequency operation. The isolated RF output ports are internally teminated to 50 . The return loss in the isolation state is limited by on-chip capacitors. Table 2.

There is no damage to device with only one parameter set at the limit and all other parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device. CAUTION: Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device. This device must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.
