Description
The SKY13408-465LF is a GaAs pHEMT single-pole, triple-throw (SP3T) high power switch with 50 Ω terminated outputs. The high linearity performance and low insertion loss achieved by the 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 configuration and package are shown in Figure 2. Signal pin assignments and functional pin descriptions are provided in Table 1.

Functional Description
Switching is controlled by three control voltage inputs, V1, V2, and V3 (pins 9, 6, and 1, respectively). Depending on the logic voltage level applied to the control pins, the RFC pin is connected to one of the three switched RF outputs (RF1, RF2, or RF3) using a low insertion loss path, while the paths between the RFC pin and the other RF pins are in a high isolation state.
DC blocking capacitors are required on all RF ports of the switch. The value of the capacitors determines the low frequency operation. The isolated RF output ports are internally teminated to 50 Ω. The return loss in the isolation state is limited by on-chip capacitors.

Note 1: Exposure to maximum rating conditions for extended periods may reduce device reliability. 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.
