V1 RFC V2 1 6 5 2 3 4 RF1 GND RF2 Description The SKY13431-374LF is a GaAs pHEMT single-pole, double-throw (SPDT) high-power switch with 50 Ω terminated outputs. The high-linearity performance and low insertion loss achieved by the SKY13431-374LF make it an ideal choice for WiMAX and higher 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 Ω impedance of the switch in the “off” 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. 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. 201649-002 Figure 2.

SKY13431-374LF Signal Descriptions Pin Name Pin Name Description RF output: 50 Ω terminated when in isolation state. Must be DC blocked. DC control voltage. A logic high voltage enables an insertion loss path between the RFC and RF1 pins. 4 RF2 RFC RF common input. Must be DC blocked. 5 GND Ground V2 DC control voltage. A logic high voltage enables an insertion loss path between the RFC and RF2 pins. RF1 RF output: 50 Ω terminated when in isolation state. Must be DC blocked. 1 V1 2 3 Description 6 Functional Description Electrical and Mechanical Specifications Switching is controlled by two control voltage inputs, V1 and V2 (pins 1 and 3, respectively). Depending on the logic voltage level applied to the control pins, the RFC pin is connected to one of the two switched RF outputs, RF1 or RF2, using a low insertion loss path, while the path between the RFC pin and the other RF pin is in a high isolation state. The absolute maximum ratings of the SKY13431-374LF are provided in Table 2. Electrical specifications are provided in Table 3. 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 is internally terminated to 50 Ω. The return loss of the isolated port is limited in frequency by onchip capacitors. Typical performance characteristics of the SKY13431-374LF are illustrated in Figures 3 through 6. The state of the SKY13431-374LF is determined by the logic provided in Table 4. 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.
