SKY13330-397LF Block Diagram Positive low control voltage range: 1.65 V to 2.70 V DC supply voltage: 2.3 V to 4.8 V Description Small QFN (12-pin, 2 x 2 mm) package (MSL1, 260 C per JEDEC J-STD-020) The SKY13330-397LF is a CMOS, silicon-on-insulator (SOI) single-pole, double-throw (SPDT) switch. The high linearity and low insertion loss of the SKY13330-397LF make it an ideal choice TM for WCDMA handset and data card applications. Skyworks Green products are compliant with all applicable legislation and are halogen-free. The switch is a reflective short on the isolated port. For additional information, refer to Skyworks The SKY13330-397LF SP2T switch is provided in a compact Quad TM Denition of Green , document number Flat No-Lead (QFN) 2 x 2 mm package. A functional block SQ040074. 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.

Functional Description Electrical and Mechanical Specifications The SKY13330-397LF is designed for medium to high power The absolute maximum ratings of the SKY13330-397LF are WCDMA handset and data card switching applications. The device provided in Table 2. Electrical specifications are provided in can also be used in a variety of other applications that require Table 3. high performance RF switching such as WLANs (a/b/g/n). The state of the SKY13330-397LF is determined by the logic An internal negative voltage generator and decoder eliminate the provided in Table 4. need for external DC blocking capacitors on the RF ports unless Typical performance characteristics of the SKY13330-397LF are VDC is externally applied. illustrated in Figures 3 through 5. Switching is controlled by one voltage input (CTRL). Depending on the logic voltage level applied to the control pin, the RF1 pin is connected to one of two switched RF outputs (RF2 or RF3) using a low insertion loss path, while the path between the RF1 pin and the other RF output pin is in a high isolation state. An internal decoder is used to provide the correct logic to the switch. Shutdown mode is enabled by connecting the ENABLE pin to logic low. Shutdown mode reduces the overall current consumption of the device to 7 A, typical. GND GND RF3 RF2 GND GND
