Description
The SKY13270-92LF is a PHEMT GaAs FET IC high-linearity SPDT switch. This wideband switch has been designed for use from 100 MHz to 2.5 GHz, where extremely high linearity, low control voltage, high isolation, low insertion loss, and ultraminiature package size are required. It can be controlled with positive, negative, or a combination of both voltages. The RF signal paths within the SKY13270-92 are fully bilateral. Some standard implementations include T/R switching and diversity switching over 3 W. The SKY13270-92LF switch can be used in many analog and digital wireless communication systems including cellular, GSM and UMTS applications. Switching is controlled via two control voltage inputs. Depending upon the voltage level applied to the control voltage pins, the common RF port (J1) is connected to one of two RF ports (J2 or J3) via a low insertion loss path, while the path between J1 and the other RF port is in its isolation state. When the control voltages are toggled, the states between J1 and J2, as well as J1 and J3, are also toggled. This part is available in a lead (Pb)-free, 6-lead SC-70 package which is RoHS-compliant. An evaluation board is available upon request.

Performance is guaranteed only under the conditions listed in the specifications table and is not guaranteed under the full range(s) described by the Absolute Maximum specifications. Exceeding any of the absolute maximum/minimum specifications may result in permanent damage to the device and will void the warranty.
CAUTION: Although this device is designed to be as robust as possible, ESD (Electrostatic Discharge) 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 must be employed at all times.
