SKY13348-374LF Block Diagram Description The SKY13348-374LF is a pHEMT GaAs Single-Pole, DoubleThrow (SPDT) high power switch with 50 Ω terminated outputs. The high linearity performance and low insertion loss achieved by the SKY13348-374LF make it an ideal choice for WiMAX and WLAN applications such as 802.11 a/b/g/n where low loss, high isolation, and excellent linearity are key requirements. The switch is manufactured in a compact, 1.5 x 1.5 mm, 6-pin exposed pad plastic Micro Leadframe Package Dual (MLPD) package. 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. V1 1 6 J1 RFC 2 5 GND V2 3 4 J2 S1532 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. Functional Description The SKY13348-374LF symmetric SPDT switch is designed using an advanced 0.5-micron GaAs pHEMT foundry process. The switch features linear power handling up to 7 watts with 50 Ω terminated outputs. Switching is controlled by two control voltage inputs, V1 and V2 (pins 1 and 3, respectively). Depending on the logic voltage level applied to the control pins, the RFC pin is connected to one of the two switched RF outputs, J1 or J2, using a low insertion loss path, while the path between the RFC pin and the other RF pin is in a high isolation state. DC blocking capacitors are required on all RF ports of the switch, and determine the lower frequency return loss and insertion loss of the insertion loss state. The off RF output is internally terminated to 50 Ω. The low frequency impedance is determined by an on-chip capacitor and cannot be extended below 500 MHz using external components. The switch is fully operational below 500 MHz. The off port impedance appears as a reflective open. If operated below 100 MHz, the power handling and linearity of the device can be degraded even at high control voltage levels. If V1 and V2 are biased to both high or low logic levels, the switch appears as a very poor two-way power splitter with low return loss on all RF ports. The switch is not damaged if placed in these states. In normal switching logic modes, V1 and V2 can be set between 1.8 and 5.0 V. The SKY13348-374LF is designed for medium to high power, dual-band WLAN, WIMAX, and LTE switching applications. The device can also be used in a variety of other applications that require high performance RF switching. The high P0.1dB and advance proprietary fabrication process enables an exceptional 3rd Order Input Intercept Point (IIP3), Error Vector Magnitude (EVM), and harmonic performance. Excellent insertion loss , return loss, and isolation are maintained up to 6 GHz. Electrical and Mechanical Specifications The absolute maximum ratings of the SKY13348-374LF are provided in Table 2. Electrical specifications are provided in Table 3. Typical performance characteristics of the SKY13348-374LF are illustrated in Figures 3 through 8.
