DATA SHEET SKY13277-355LF: GaAs SP3T Absorptive Switch 500 MHz–2.5 GHz Features Functional Diagram Positive voltage control (0/3 V typ.) ● High isolation 62 dB at 1 GHz ● Integrated silicon CMOS driver ● Isolated ports are absorptive ● Available lead (Pb)-free and RoHS-compliant MSL-1 @ 260°C per JEDEC J-STD-020 ● J1 RFc J2 J3 Description VCT2 VCT1 Decoder VDD The SKY13277-355LF is a pHEMT GaAs FET IC high isolation absorptive single-pole 3-throw switch packaged in a 20-lead exposed-pad plastic package for low-cost commercial applications. This switch controls signals from 500 MHz to 2.5 GHz. The switch is ideal for cellular base station switch matrices and other applications that require good RF impedance match independent of switch state. The SKY13277-355LF comprises a pHEMT switch die and a Si CMOS controller die. The switch die contains integral terminating resistors that present an absorptive load to the external circuit when the switch path is in its isolation state. The controller die has three inputs: supply voltage (VDD) and two logic control bits that select the state of the pHEMT switch die. External DC block capacitors are required on all RF ports. The SKY13277-355LF operates from -40 °C to 85 °C. A populated evaluation board is available. NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances)-compliant packaging.

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.
