Description
Skyworks SKY73009 is an integrated, broadband, high-dynamic
range quadrature demodulator for use in various wireless
communication system applications. The SKY73009 can perform
quadrature demodulation of RF input signals from 400 to
3000 MHz directly to baseband frequencies. The quadrature
outputs are differential and can be directly connected to most
commonly available A/D converters.
The high dynamic range and second order Input Intercept Point
(IIP2) value of the SKY73009 make it ideal for use in direct
conversion and low Intermediate Frequency (IF) receivers.
Figure 1 shows a functional block diagram for the SKY73009. The
device package and pinout for the 32-pin RF Land Grid Array
(RFLGA) are shown in Figure 2.
Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances) compliant packaging.

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 values.
Equivalent Input Circuits
An equivalent circuit for the RF input of the SKY73009 is shown in
Figure 3. The equivalent circuit for the Local Oscillator (LO) input
is shown in Figure 4. An internal balun is used to convert the
single-ended LO input into a differential signal before being
buffered inside the device.
Electrical and Mechanical Specifications
Signal pin assignments and functional pin descriptions are
provided in Table 1. The absolute maximum ratings of the
SKY73009 are provided in Table 2 and the recommended
operating conditions provided in Table 3. Electrical characteristics
of the SKY73009 are provided in Table 4.
The typical performance of the SKY73009 with respect to
frequency is illustrated in Figures 5 through 54. Figure 62
provides the package dimensions for the 32-pin RFLGA, and
Figure 63 provides the tape and reel dimensions.
Package and Handling Information
Since the device package is sensitive to moisture absorption, it is
baked and vacuum packed before shipping. 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.
The SKY73009 is rated to Moisture Sensitivity Level 3 (MSL3) at
260 °C. It can be used for lead or lead-free soldering. For
additional information, refer to the Skyworks Application Note,
PCB Design & SMT Assembly/Rework Guidelines for RFLGA
Packages, document number 103147.

Evaluation Board Description
The SKY73009 Evaluation Board is used to test the performance
of the SKY73009 direct quadrature demodulator. There are three
Evaluation Boards for this device, each configured for a specific
frequency range. Schematic diagrams and Bills of Materials
(BOMs) for each board are presented in the following Figures and
Tables:
• Figure 55 and Table 5 (800-1000 MHz)
• Figure 56 and Table 6 (1500-2500 MHz)
• Figure 57 and Table 7 (custom frequency)
The Evaluation Board assembly diagram is shown in Figure 58
(800-1000 MHz), Figure 59 (1500-2500 MHz), and Figure 60
(custom frequency).
Circuit Design Considerations
The following design considerations are general in nature and
must be followed regardless of final use or configuration.
1. Paths to ground should be made as short as possible.
2. The ground pad of the SKY73009 direct quadrature
demodulator has special electrical and thermal grounding
requirements. This pad is the main thermal conduit for heat
dissipation. Since the circuit board acts as the heat sink, it
must shunt as much heat as possible from the device. As
such, design the connection to the ground pad to dissipate the
maximum wattage produced to the circuit board.
3. Two external output bypass capacitors are required on the
VCC pin. The values of these capacitors will change with
respect to the desired RF frequency. One capacitor should be
used for low frequency bypassing and the other capacitor for
high frequency bypassing. Special attention should be given
so that the smaller value capacitor does not go into self-
resonance at the desired RF frequency.
4. The RF input must be driven differentially. A 1:1 impedance
ratio balun is recommended with a center tap on the
secondary side that is DC grounded.
Testing Procedure
Use the following procedure to set up the SKY73009 Evaluation
Board for testing. Refer to Figure 61 for guidance:
1. Connect a +3.0 VDC power supply using an insulated supply
cable. If available, enable the current limiting function of the
power supply to 100 mA.
2. Connect a signal generator to the RF signal input port. Set it to
the desired RF frequency at a power level of 0 dBm to the
Evaluation Board but do NOT enable the RF signal.
3. Connect a signal generator to the LO signal input port. Set to
the desired LO frequency at a power level of 0 dBm, but do
not enable.
4. Connect a spectrum analyzer to the IFI signal output port and
terminate the IFQ signal input port in 50 Ω.
5. Enable the power supply.
6. Enable the LO input signal.
7. Enable the RF signal.
8. Take measurements and repeat these steps for channel Q.
CAUTION: If any of the input signals exceed the rated maximum
values, the SKY73009 Evaluation Board can be
permanently damaged.
