SKY13321-360LF Block Diagram +39 dBm Small, QFN (8-pin, 2 x 2 mm) package (MSL1, 260 C per Description JEDEC J-STD-020) The SKY13321-360LF is a pHEMT GaAs FET I/C switch. The switch may be used in transmit/receive applications by connecting the RF common port (RFC, pin 7) to either the J1 or J2 port (pin 1 or 4, respectively) using a low loss path (i.e., a positive voltage applied to either V1 or V2 pins). The switch is manufactured in a compact, 2 x 2 mm, 8-pin exposed pad plastic 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. 1 J1 8 V1 2 7 GND RFC 6 3 GND GND 4 5 J2 V2 S1420 Figure 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. 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.
