SKY13290-313LF Block Diagram Description The SKY13290-313LF is a high power, pHEMT Single Pole Double Throw (SPDT) switch. The switch is designed for use in systems operating from 20 MHz to 2.5 GHz for which low loss, high isolation, low control voltage, and ultra-miniature package size are required. The device is controlled with positive, negative, or a combination of both voltages. The RF signal paths within the device are fully bilateral. The SKY13290-313LF is manufactured in a compact, low-cost 2 x 3 mm, 6-pin Quad Flat No-Lead (QFN) 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. Figure 2.

According to the logic voltage levels applied to the V1 and V2 pins, this port is either connected to J1 using a low insertion loss path or isolated from J1 (Note 1). 4 V2 DC control voltage input #2. The logic voltage applied to this pin, along with the voltage level applied to the V1 pin, determines the states of the RF paths between J1/J2 and J1/J3. 2 GND Ground. Equipotential port, internal circuit common, which must connected to the PCB ground or common using the lowest possible impedance. 5 J1 RF input/output. According to the logic voltage levels applied to the V1 and V2 pins, this port is either connected to J2 or to J3 using a low insertion loss path and isolated from the other RF port (Note 1). 3 J3 RF input/output. According to the logic voltage levels applied to the V1 and V2 pins, this port is either connected to J1 using a low insertion loss path or isolated from J1 (Note 1). 6 V1 DC control voltage input #1. The logic voltage applied to this pin, along with the voltage level applied to the V2 pin, determines the states of the RF paths between J1/J2 and J1/J3. Note 1: A 47 pF blocking capacitor is required for >500 MHz operation. Use larger value capacitors for lower frequency operation. Table 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. 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. Technical Description Electrical and Mechanical Specifications The SKY13290-313LF is controlled using two voltage inputs, V1 and V2 (pins 6 and 4, respectively). Depending on the voltage level applied to these pins, the common RF port (J1) is connected to one of two RF ports (J2 or J3) using a low insertion loss path, while the path between J1 and the other RF port is in its isolation state. The absolute maximum ratings of the SKY13290-313LF are provided in Table 2. Electrical specifications are provided in Table 3 and the operating characteristics are specified in Table 4. When the control voltages are toggled, the states between J1 and J2, as well as J1 and J3, are also toggled. Typical performance characteristics of the SKY13290-313LF are illustrated in Figures 3 through 6. The state of the SKY13290-313LF is determined by the logic provided in Table 5.
