SKY13575-639LF Block Diagram Description The SKY13575-639LF is a dual-band single-pole, four-throw switch with an integrated 50 match on all RF output ports. External DC blocking capacitors are required on the RF paths. The switch can operate over the temperature range of 40C to 90 C. Switching is controlled by two CMOS/TTL compatible control voltage inputs: VC1 and VC2. Depending upon the logic voltage level applied to the control pins, the RFC pin is connected to one of four switched RF outputs (RF1 to RF4) by a low insertion loss path, while the path between the RFC pin and the other RF pins is in isolation. The isolated ports are terminated to a 50 load.

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.
