Functional Description The SKY13348-374LF symmetric SPDT switch is designed using If V1 and V2 are biased to both high or low logic levels, the switch an advanced 0.5-micron GaAs pHEMT foundry process. The appears as a very poor two-way power splitter with low return switch features linear power handling up to 7 watts with 50 loss on all RF ports. The switch is not damaged if placed in these terminated outputs. Switching is controlled by two control voltage states. In normal switching logic modes, V1 and V2 can be set inputs, V1 and V2 (pins 1 and 3, respectively). Depending on the between 1.8 and 5.0 V. logic voltage level applied to the control pins, the RFC pin is The SKY13348-374LF is designed for medium to high power, connected to one of the two switched RF outputs, J1 or J2, using dual-band WLAN, WIMAX, and LTE switching applications. The a low insertion loss path, while the path between the RFC pin and device can also be used in a variety of other applications that the other RF pin is in a high isolation state. require high performance RF switching. The high P0.1dB and DC blocking capacitors are required on all RF ports of the switch, advance proprietary fabrication process enables an exceptional and determine the lower frequency return loss and insertion loss third order input intercept point (IIP3), error vector magnitude of the insertion loss state.

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.
