Power Derating, Maximum CW Incident Power (Insertion Loss = 0.2 dB) vs Temperature on Bottom of Printed Circuit Board Evaluation Board Description The SKY12211-478LF Evaluation Board is used to test the performance of the SKY12211-478LF PIN Diode SPDT switch. An assembly drawing for the Evaluation Board is shown in Figure 14. The layer detail is provided in Figure 15. The SKY12211-478LF 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 11, 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 12. The evaluation circuit is designed to facilitate control of the SKY12211-478LF SPDT switch with bias signals derived from positive voltages. The state of the PIN diodes within the SKY12211-478LF is controlled with 5 V applied to the RFC port and bias voltages of either 28 V or 0 V applied to the remaining bias inputs (RF1 and RF2 ports). The switch state circuit diagrams are shown in Figure 13. The values of resistors R2 and R3 (refer to the schematic diagram in Figure 16), which are both nominally 540 Ω, together with the magnitudes of the voltages applied to the RF1 and RF2 ports, determine which of the two series of diodes is biased into conduction and how much current flows through the forward biased diode. For example, to place the SKY12211-478LF into the RFC to RF1 low insertion loss state, 0 V is applied to the RF1 port (which forward biases the diode between pins 2 and 14), 28 V is applied to the RF2 port (which reverse biases the diode between pins 2 and 7), 0 V is applied to the RF2_BIAS port (which applies a forward bias through R3 to the diode connected between pins 7 and 9), and 28 V is applied to the RF1_BIAS port (which applies a forward bias through R2 to the diode connected between pins 14 and 11). The values of R2 and R3 may be adjusted to accommodate other bias voltages. Resistance values of 540 Ω are selected to Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • [email protected] • www.skyworksinc.com 8 January 27, 2014 • Skyworks Proprietary Information • Products and Product Information are Subject to Change Without Notice • 201711E DATA SHEET • SKY12211-478LF 40 W PIN DIODE SPDT SWITCH produce approximately 50 mA of forward bias current in the diodes, which are forced into conduction when the bias source voltage is 28 V. The component values shown in the Evaluation Board circuit diagram (Figure 16) were selected to optimize performance in the 0.05 to 2.70 GHz band. Refer to Table 8 for the Evaluation Board Bill of Materials. Table 9 provides voltage, current, and resistor values for bias adjustments. Package Dimensions The PCB layout footprint for the SKY12211-478LF is shown in Figure 17. Typical case markings are noted in Figure 18. Package dimensions for the 16-pin QFN are shown in Figure 19, and tape and reel dimensions are provided in Figure 20.
