SKYA21024 Block Diagram Single bit control Automotive Level-3 PPAP available upon request Description IMDS material declaration available at production release The SKYA21024 is a single-pole, double-throw (SPDT) switch Extended production life to support automotive requirements intended for mode switching in pre-power amplifier (PA) cellular Independent BOM management to minimize PCN risk or WLAN applications. Using advanced switching technologies, the SKYA21024 maintains low insertion loss and high isolation for Small QFN (6-pin, 1 x 1 mm) package all switching paths. (MSL1, 260 C per JEDEC J-STD-020) The high linearity performance and low insertion loss achieved by TM the switch make it an ideal choice for mode switching before the Skyworks Green products are compliant with PA in cellular applications. Depending on the logic voltage applied all applicable legislation and are halogen-free. to the control pin (VCTL), the RFC pin is connected to one of the For additional information, refer to Skyworks TM two switched RF outputs, RF1 or RF2, using a low insertion loss Denition of Green , document number path, while the path between the RFC pin and the other RF path is SQ040074. in a high isolation state. The switch is manufactured in a compact, 1 x 1 mm, 6-pin 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.

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.
