Description
The SKY12208-478LF is a high power handling, Single-Pole,
Double-Throw (SPDT) silicon PIN diode switch. The device can
cover two frequency bands, 0.02 to 0.70 GHz or 0.05 to 2.7 GHz,
by changing the value of an RF choke in the SMT bias network.
The different Evaluation Board components for each band are
noted in Table 10.
The SKY12208-478LF features low insertion loss, excellent power
handling, and superb linearity with low DC power consumption.
The device is well-suited for use as a high power transmit/receive
switch in a variety of telecommunication systems.
The device is provided in a 4 x 4 mm, 16-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.

Electrical and Mechanical Specifications
The absolute maximum ratings of the SKY12208-478LF are
provided in Table 2. Recommended operating conditions are
specified in Table 3 and electrical specifications are provided in
Table 4 (28 V bias @ 0.25 GHz), Table 5 (5 V bias @ 0.25 GHz),
Table 6 (5 V bias @ 2.0 GHz), and Table 7 (28 V bias @ 2.0 GHz).
The state of the SKY12208-478LF is determined by the logic
provided in Table 8. Table 9 provides the logic for use with the
SKY12208-478LF Evaluation Board.
Power derating data is plotted against temperature in Figures 19
and 20. Equivalent circuit diagrams for transmit and receive are
shown in Figure 21.
Typical performance characteristics of the SKY12208-478LF are
illustrated in Figures 3 through 8 (0.25 GHz) and Figures 9
through 18 (2.0 GHz).

Note:
Exposure to maximum rating conditions for extended periods may reduce device reliability. 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.

Evaluation Board Description
The SKY12208-478LF Evaluation Board is used to test the
performance of the SKY12208-478LF PIN Diode SPDT switch. An
assembly drawing for the Evaluation Board is shown in Figure 22.
The layer detail is provided in Figure 23.
The SKY12208-478LF 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 19, 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 20.
The evaluation circuit is designed to facilitate control of the
SKY12208-478LF transmit/receive switch with bias signals
derived from positive voltages. The state of the PIN diodes within
the SKY12208-478LF 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 21.
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 SKY12208-478LF
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).

Package and Handling Information
The component values shown in the Evaluation Board circuit
diagram (Figure 24) were selected to optimize performance in the
0.02 to 0.70 GHz and 0.05 to 2.7 GHz bands.
Instructions on the shipping container label regarding exposure to
moisture after the container seal is broken must be followed.
Otherwise, problems related to moisture absorption may occur
when the part is subjected to high temperature during solder
assembly.
Refer to Table 10 for the Evaluation Board Bill of Materials.
Table 11 provides voltage, current, and resistor values for bias
adjustments.
The SKY12208-478LF is rated to Moisture Sensitivity Level 1
(MSL1) at 260 C. It can be used for lead or lead-free soldering.
For additional information, refer to the Skyworks Application Note,
Solder Reflow Information, document number 200164.
Package Dimensions
The PCB layout footprint for the SKY12208-478LF is shown in
Figure 25. Typical case markings are noted in Figure 26. Package
dimensions for the 16-pin QFN are shown in Figure 27, and tape
and reel dimensions are provided in Figure 28.
Care must be taken when attaching this product, whether it is
done manually or in a production solder reflow environment.
Production quantities of this product are shipped in a standard
tape and reel format.

Note 1: Component values selected are based on the desired frequency and bias level. Values may be adjusted for a specific response.
Note 2: Two 160 Ω resistors are combined in parallel to achieve a minimum power handling requirement and 80 Ω resistance.
Note 3: Evaluation Board does not include resistor R2. Operating at 28 V and 50 mA requires resistor R2 with a power dissipation greater than 1.35 W.

Notes: VS = supply voltage; VDIODE = voltage drop across the diode; VRES = voltage drop across the resistor.
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). The resistor selected must be
safely rated with a power greater than the dissipated power.
