Description
The SKY73020 is a fully integrated diversity mixer that includes
Local Oscillator (LO) drivers, an LO switch, high linearity mixers,
and large dynamic range Intermediate Frequency (IF) amplifiers.
Low-loss RF baluns have also been included to reduce design
complications and lower system cost.
The SKY73020 features an input IP3 of 27.0 dBm and a Noise
Figure (NF) of 10.2 dB, making the device an ideal solution for
high dynamic range systems such as 2G/3G base station
receivers. The LO switch provides more than 65 dB of isolation
between LO inputs and supports the switching time required for
GSM/EDGE base stations.
The SKY73020 is manufactured using a robust silicon BiCMOS
process and has been designed for optimum long-term reliability.
The SKY73020 diversity downconversion mixer is provided in a
compact, 36-pin 6 x 6 mm Multi-Chip Module (MCM). 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.
Skyworks offers lead (Pb)-free RoHS (Restriction of
Hazardous Substances) compliant packaging.

Evaluation Board Description
The SKY73020 Evaluation Board is used to test the performance
of the SKY73020 downconversion mixer. An assembly drawing for
the Evaluation board is shown in Figure 41 and the layer detail is
provided in Figure 42.
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 and as low
impedance as possible.
2. The ground pad of the SKY73020 provides critical electrical
and thermal functionality. 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. Therefore, design the connection to the ground
pad to dissipate the maximum heat produced by the circuit
board. For more information on soldering the SKY73020, refer
to the Package and Handling Information section of this Data
Sheet.
3. Skyworks recommends including external bypass capacitors
on the VCC voltage inputs of the device.
4. Components L5, L6, L14, and L15 (see Figure 3) are high-Q,
low-loss inductors. These inductors must be able to pass
currents in excess of 200 mA DC.
5. Components R1 and R2 (see Figure 3) allow for external
adjustment of the IF amplifier bias points. For operation as
specified in Tables 3 and 4, these resistors are not required.
A schematic diagram for the SKY73020 Evaluation Board is
shown in Figure 43.
