The SKY13354-368LF is a pHEMT GaAs dual single-pole, double- For additional information, refer to Skyworks throw (SPDT) crossed switch designed for cellular infrastructure Denition of Green, document number band switching applications. The internal crossed switch SQ04-0074. arrangement is designed to switch balanced RF filters. Switching is controlled by two control voltage inputs (V1 and V2). Depending on the logic voltage level applied to the control pins, the RFCA and RFCB pins are each connected to one of four 12 11 10 switched RF outputs (RF1A, RF1B, RF2A, or RF2B) using a low insertion loss path, while maintaining a high isolation path to the RF1B RFCA 1 9 alternate port DC blocking capacitors are required on all RF ports. The switch is a reflective short on the isolated port. N/C 2 8 N/C The switch is manufactured in a compact, 2 x 2 mm, 12-pin exposed pad plastic Quad Flat No-Lead (QFN) package.

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.
