SKY13431-374LF Block Diagram Description TM Skyworks Green products are compliant with The SKY13431-374LF is a GaAs pHEMT single-pole, double-throw all applicable legislation and are halogen-free. (SPDT) high-power switch with 50 terminated outputs. The For additional information, refer to Skyworks high-linearity performance and low insertion loss achieved by the TM Denition of Green , document number SKY13431-374LF make it an ideal choice for WiMAX and higher SQ04-0074. power WLAN applications such as access points. This part is designed for use in WLAN systems using discrete power amplifier (PA) and low-noise amplifier (LNA) implementations. The 50 impedance of the switch in the off V1 1 6 RF1 state ensures good isolation regardless of the match to which the switch is connected. The SKY13431-374LF is manufactured in a compact, 1.5 x 1.5 mm, 6-pin Dual Flat No-Lead (DFN) package. RFC 2 5 GND A functional block diagram is shown in Figure 1.

Functional Description Electrical and Mechanical Specifications Switching is controlled by two control voltage inputs, V1 and V2 The absolute maximum ratings of the SKY13431-374LF are (pins 1 and 3, respectively). Depending on the logic voltage level provided in Table 2. Electrical specifications are provided in applied to the control pins, the RFC pin is connected to one of the Table 3. two switched RF outputs, RF1 or RF2, using a low insertion loss Typical performance characteristics of the SKY13431-374LF are path, while the path between the RFC pin and the other RF pin is illustrated in Figures 3 through 6. in a high isolation state. The state of the SKY13431-374LF is determined by the logic DC blocking capacitors are required on all RF ports of the switch. provided in Table 4. The value of the capacitors determines the low frequency operation. The isolated RF output is internally terminated to 50 . The return loss of the isolated port is limited in frequency by on- chip capacitors. 1 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. ESD HANDLING: 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 when handling or transporting. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD handling precautions should be used at all times. Skyworks Solutions, Inc.
