R1 Termination 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 must be employed at all times. CBL = 39 pF for operation >500 MHz. R1 = 39 Ω. Exposed paddle on bottom of package needs to be connected to ground. Pin Descriptions Pin Number 1 Pin Name V1 Description Control voltage 1 - Control Voltage Input #1. The logic level voltage applied to this pin, along with the level voltage applied to pin 4, determines the states of the RF paths between the Tx, Rx and Ant ports. Equipotential point - Internal circuit common which must be connected to the pcb ground or common via the lowest possible impedance. RF input/output. Control voltage 2 - Control Voltage Input #2. The logic level voltage applied to this pin, along with the level voltage applied to pin 1, determines the states of the RF paths between the Tx, Rx and Ant ports. An external termination resistor must be added to this pin for the Tx port to be matched when Tx-Ant path is in its isolation state. RF input/output. Equipotential point - Internal circuit common which must be connected to the pcb ground or common via the lowest possible impedance. RF input/output. 2 GND Applications The SKY13274-349LF is designed for use as an UWB TR switch for signal frequencies up to 6 GHz. When the switch is in its receive state with the voltage at pin 1 (V1) low and the voltage at pin 4 (V2) high, the Tx input port is terminated via an external resistor connected between pin 5 (R1) and ground. A 39 Ω external resistor in this position produces a 50 Ω (nominal) impedance looking into pin 6. DC blocking capacitors are required at each of the RF ports. The nominal value for these capacitors is 39 pF This value should be increased for operation with RF at frequencies below 500 MHz. The exposed paddle on the back side of the package must be grounded for proper operation. 8 Rx 3 4 Ant V2 5 Termination 6 7 Tx GND Truth Table V1 Low High Low High V2 High Low Low High Rx-Ant Ins.
