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.
The evaluation circuit is designed to facilitate control of the
SKY12207-306LF transmit/receive switch with bias signals

Figure 19. SKY12207-306LF Equivalent Circuit Diagrams
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).
