DATA SHEET SKY13522-644LF: 0.7 to 6.0 GHz High-Isolation (Single-Bit-Control) SPDT Switch Applications GSM/DCS/PCS/CDMA/WCDMA/TD-SCDMA single-ended filter switching Features Broadband frequency range: 0.7 to 6.0 GHz High isolation: 47 dB 2.2 GHz (typical) Single bit control Small QFN (8-pin,1.1 x 1.1 x 0.45 mm) package (MSL1, 260 C per JEDEC J-STD-020) Figure 1. SKY13522-644LF Block Diagram Description The SKY13522-644LF is a single-pole, double-throw (SPDT) switch used for single-ended switching in cellular applications. Using advanced switching technologies, the SKY13522-644LF maintains low insertion loss and high isolation for all switching paths. Depending on the logic voltage level applied to the control pin (V1), the antenna port (RFC) is connected to one of two switched RF outputs (RF1 or RF2) through a low insertion loss path, while the path between the antenna port and the other RF port is in a high isolation state. The SKY13522-644LF is provided in a small 8-pin, 1.1 x 1.1 mm 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 Figure 2. SKY13522-644LF Pinout assignments and functional pin descriptions are provided in (Top View) Table 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. 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.
