DATA SHEET SKY13398-000: 0.02 – 6.0 GHz pHEMT GaAs SP3T Switch Applications • 802.11 a/b/g/n WLAN networks • Bluetooth® systems Features • Positive low voltage control: 0/1.8 to 5.0 V • Low insertion loss: 0.8 dB @ 2.5 GHz • Excellent linearity performance: P1dB = +33 dBm • Advanced pHEMT process • Bare pHEMT die: 650 x 450 x 127 μm Figure 1. SKY13398-000 Block Diagram Description The SKY13398-000 is a GaAs pHEMT Single-Pole, Triple-Throw (SP3T) antenna switch that operates in the 0.1 to 6.0 GHz frequency range. Switching between the antenna (RFC signal) and the RF1, RF2, and RF3 ports is accomplished with three control voltages (VC1, VC2, and VC3). This switch is a reflective short when in the isolation state. The low loss, high isolation, high linearity, small size, and low cost make this switch ideal for all WLAN and Bluetooth systems operating in the 2.4 to 2.5 and 4.9 to 5.9 GHz bands. The SKY13398-000 is provided as a bare die in an ultra-compact 650 x 450 x 127 μm design. A functional block diagram is shown in Figure 1. The pin configuration and package are shown in Figure 2. Signal pin assignments and functional pin descriptions are provided in Table 1. Figure 2.

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. Electrical and Mechanical Specifications The absolute maximum ratings of the SKY13398-000 are provided in Table 2. Electrical specifications are provided in Table 3. The state of the SKY13398-000 is determined by the logic provided in Table 4. Typical performance characteristics of the SKY13398-000 are illustrated in Figures 3 through 6.
