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.

Transmit Power Derating, Maximum CW Incident Power (Insertion Loss = 0.3 dB) vs Temperature on Bottom of Printed Circuit Board Evaluation Board Description The SKY12207-306LF Evaluation Board is used to test the performance of the SKY12207-306LF PIN Diode SPDT switch. An assembly drawing for the Evaluation Board is shown in Figure 20. The layer detail is provided in Figure 21. The SKY12207-306LF is designed to handle very large signals. Sufficient power may be dissipated by this switch to cause heating of the PIN diodes contained in the switch. It is very important to use a printed circuit board design that provides adequate cooling capability to keep the junction temperature of the PIN diodes below their maximum rated operating temperature. As indicated in Figure 17, the x-axis temperature is referenced to the bottom of the QFN package. A printed circuit board with a very low thermal resistance and external heat sink design must be used to achieve the results shown in this Figure. The power derating curve with the x-axis temperature referenced to the bottom of the printed circuit board is provided in Figure 18. derived from positive voltages. The state of the PIN diodes within the SKY12207-306LF is controlled with 5 V applied to the ANT port and bias voltages of either 28 V or 0 V applied to the remaining bias inputs (RX and TX ports). The switch state circuit diagrams are shown in Figure 19. The value of resistor R1, 80 Ω, is selected to provide 50 mA of forward current through the "on" series diode with 5 V applied to the ANT port bias pin. The R2 resistance value of 540 Ω is selected to produce approximately 50 mA of forward bias current in the RX shunt diode with a source voltage of 28 V. The magnitudes of the voltages applied to the TX and RX ports determine which of the RX or TX series diodes is biased into forward conduction. For example, to place the SKY12207-306LF into the transmit state, 0 V is applied to the TX port (which forward biases the diode between pins 2 and 14), 28 V is applied to the RX port (which reverse biases the diode between pins 2 and 7), and 0 V is applied to the RX_BIAS port (which applies a forward bias through R2 to the diode connected between pins 7 and 9). The evaluation circuit is designed to facilitate control of the SKY12207-306LF transmit/receive switch with bias signals Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • [email protected] • www.skyworksinc.com 201517L • Skyworks Proprietary Information • Products and Product Information are Subject to Change Without Notice • August 1, 2014 11 DATA SHEET • SKY12207-306LF: 50 W PIN DIODE SPDT SWITCH Package and Handling Information The component values shown in the Evaluation Board circuit diagram (Figure 22) were selected to optimize performance in the 2.0 to 3.5 GHz band.

R1 and R2 values are calculated by (Vs – VDIODE)/I, where I is the desired bias current. The power dissipation in R1 or R2 is calculated by I x (VS – VDIODE).
