DATA SHEET SKY13278-313LF: GaAs SPDT Switch 100 MHz-2.5 GHz Features G G G G G G Function Block Diagram J2 V1 Broadband: 100 MHz-2.5 GHz Very low insertion loss: 0.4 dB typ. @ 900 MHz High isolation: 26 dB typ. @ 900 MHz Low current consumption: <100 A @ 3 V Miniature QFN-6 2 x 3 mm package Lead (Pb)-free and RoHS-compliant MSL-1 @ 260 C per JEDEC J-STD-020 J1 J3 V2 Description The SKY13278-313LF 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 ultra-miniature package size are required. It can be controlled with positive, negative or a combination of both voltages. The RF signal paths within the SKY13278-313LF are fully bilateral. Some standard implementations include T/R switching and diversity switching over 3 W. The SKY13278-313LF 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 wells as J1 and J3, are also toggled. The SKY13278-313LF is available in a lead(Pb)-free, RoHS-compliant, QFN-6 2 x 3 mm plastic package. An evaluation board is available upon request. NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances)-compliant packaging.

Switch is in an undefined state. Recommended Solder Reflow Profiles Refer to the "Recommended Solder Reflow Profile" Application Note. 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. Tape and Reel Information Refer to the "Discrete Devices and IC Switch/Attenuators Tape and Reel Package Orientation" Application Note. 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. Skyworks Solutions, Inc. * Phone [781] 376-3000 * Fax [781] 376-3100 * sales@skyworksinc.com * www.skyworksinc.com 200504 Rev.

D DATA SHEET * SKY13278-313LF Evaluation Board The evaluation board for the SKY13278-313 allows the switch to be fully exercised. The RF common port is marked "J1", and the two switched RF ports are marked "J2" and "J3". All of the RF ports have SMA connectors mounted. The control voltage inputs are marked "V1" and "V2". The printed circuit board material is FR4. The RF dielectric layer is 0.012 inches thick, 1/2 oz. copper. The RF transmission lines are each 50 (nominal) microstrip. There are three DC blocking capacitors on the board, C1, C2 and C3, each of which is in series with one of the RF ports. These capacitors are 47 pF. For improved insertion loss at signal frequencies below approximately 500 MHz these capacitors should be replaced with larger capacitance capacitors, such as 1000 pF.
