SKY13278-313LF Block Diagram (MSL1, 260 C per JEDEC J-STD-020) Description TM Skyworks Green products are compliant with The SKY13278-313LF is a pHEMT GaAs FET IC high linearity all applicable legislation and are halogen-free. SPDT switch. This wideband switch has been designed for use For additional information, refer to Skyworks TM from 100 MHz to 2.5 GHz, where extremely high linearity, low Denition of Green , document number control voltage, high isolation, low insertion loss and ultra- SQ040074. miniature package size are required. It can be controlled with positive, negative or a combination of both voltages. The RF signal paths within the SKY13278-313LF are fully bilateral. Some standard implementations include T/R switching and diver- J2 1 6 V1 sity switching over 3 W. The SKY13278-313LF switch can be used in many analog and digital wireless communication systems including cellular, GSM and UMTS applications. Switching is controlled via two control voltage inputs. Depending 2 GND 5 J1 upon the voltage level applied to the control voltage pins, the common RF port (J1) is connected to one of two RF ports (J2 or J3) via a low insertion loss path, while the path between J1 and the other RF port is in its isolation state. When the control 3 4 J3 V2 voltages are toggled, the states between J1 and J2, as wells as J1 and J3, are also toggled. The SKY13278-313LF is available in a lead(Pb)-free, RoHS-com- 200504-002 pliant, QFN-6 2 x 3 mm plastic package.A functional block Figure 2. SKY13278-313LF Pinout diagram is shown in Figure 1.

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. 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.
