SKY8560- Block Diagram The SKY8560- is an integrated, single-pole double-throw (SPDT) switch with a low-noise amplifier (LNA) intended for wireless applications. The device has a low noise figure (NF) with high linearity in the transmit mode. The SKY8560- operates at. V and draws 5 ma of current. In the transmit mode, a shutdown function saves power when the device is inactive. The switch requires five external components. The switch is manufactured in a compact,.5 x.5 mm, 6-pin Quad Flat No-Lead (QFN) package. The small footprint provides the industry s smallest PCB area needed to implement an integrated broadband SPDT switch with LNA functionality. A functional block diagram is shown in Figure. The pin configuration and package are shown in Figure. Signal pin assignments and functional pin descriptions are provided in Table. RX 0 C0 9 5 6 7 8 C VDD TX 0770-00 Figure.

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. Table.
