SKY13374-397LF Block Diagram (VBATT) Small, QFN (12-pin, 2 x 2 mm) package Description (MSL1, 260 C per JEDEC J-STD-020) The SKY13374-397LF is a CMOS silicon-on-insulator (SOI) single- pole, double-throw (SPDT) WCDMA band switch. The TM high-linearity performance and low insertion loss achieved by the Skyworks Green products are compliant with device makes it an ideal choice for medium to high power all applicable legislation and are halogen-free. WCDMA handset and data card applications. For additional information, refer to Skyworks TM Denition of Green , document number The high 0.1 dB input compression point (IP0.1dB) and advance SQ040074. proprietary fabrication process enable exceptional WCDMA harmonic and adjacent channel power (ACP) performance. Excellent insertion loss and isolation is maintained over WCDMA bands 1 to 6 and 8 to 11. The SKY13374-397LF SPDT switch is provided in a compact 12 11 10 Quad Flat No-Lead (QFN) 2 x 2 mm package with 0.5 mm lead pitch for ease of manufacturing. A functional block diagram is shown in Figure 1. The pin configuration and package are shown N/C VBATT 1 9 in Figure 2. Signal pin assignments and functional pin descriptions are provided in Table 1.

Functional Description Electrical and Mechanical Specifications Switching is controlled by two control voltage inputs (V1 and V2). The absolute maximum ratings of the SKY13374-397LF are Depending on the logic voltage level applied to these pins, the provided in Table 2. Electrical specifications are provided in RF1 pin is connected to one of two switched RF outputs (RF2 or Table 3.

An internal negative voltage generator and decoder eliminate the Typical performance characteristics of the SKY13374-397LF are need for external DC blocking capacitors on the RF ports. No illustrated in Figures 3 through 5. external components are required for proper operation. DC decoupling capacitors may be added on the VBATT and control lines if necessary. Shutdown mode is enabled by connecting both control pins (V1 and V2) to logic low. This mode reduces the overall current consumption of the device to 5 A typical. Table 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.
