Description
Skyworks SKY73001 direct conversion mixer is an integrated,
high-dynamic range, zero Intermediate Frequency (IF)
architecture down-converter for use in wireless communication
applications. High second and third order input intercept points
(IIP2 and IIP3, respectively) allow seamless integration into high
performance systems. The SKY73001 has a wide RF and Local
Oscillator (LO) frequency range of 2 to 3500 MHz.
Figure 1 shows a functional block diagram for the SKY73001. 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.

DATA SHEET • SKY73001 DIRECT CONVERSION MIXER
Evaluation Board Description
ThwewSwK.DY7a3ta0S0h1eEevt4aUlu.caotimon Board is used to test the performance
of the SKY73001 direct conversion mixer. An Evaluation Board
schematic diagram (500-2500 MHz) is shown in Figure 8.
Evaluation Board assembly diagrams are shown in Figure 9
(2-2500 MHz) and Figure 10 (3200-3500 MHz). Bills of Material
(BOMs) are provided in Table 5 (2-500 MHz and 500-2500 MHz)
and Table 6 (3200-3500 MHz).
Circuit Design Configurations
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 SKY73001 direct conversion mixer 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 mixer. As such, design the
connection to the ground pad to dissipate the maximum
wattage produced to the circuit board. Multiple vias to the
grounding layer are required.
3. Two external output bypass capacitors are required on the
VCC pins. 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. Wire wound balanced transformers (baluns) were used during
the test and characterization of the SKY73001. Ceramic
baluns can be used to create the differential input signals (i.e.,
RF and LO). However, their performance will limit the overall
system performance of the SKY73001.
Testing Procedure
Use the following procedure to set up the SKY73001 Evaluation
Board for testing. Refer to Figure 11 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 LOQ 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 IFQ signal output port and
terminate the IFI 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 I.
CAUTION: If any of the input signals exceed the rated maximum
values, the SKY73001 Evaluation Board can be
permanently damaged.
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 SKY73001 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.
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. For packaging details, refer to the Skyworks
Application Note, Tape and Reel, document number 101568.
Electrostatic Discharge (ESD) Sensitivity
The SKY73001 is a static-sensitive electronic device. Do not
operate or store near strong electrostatic fields. Take proper ESD
precautions.
