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
2. The ground pad of the SKY73100 provides critical electrical
3. Skyworks recommends including external bypass capacitors
4. A 50 Ω impedance trace is needed for the RF_OUT (pin 10)

Electrical and Mechanical Specifications
The absolute maximum ratings of the SKY73100 are provided in
Table 3. The recommended operating conditions are specified in
Table 4 and electrical specifications are provided in Table 5. Spur
suppression measurements are provided in Table 6.
Measurement plots for single sideband phase noise and settling
time are shown in Figures 5 and 6, respectively.
A typical application schematic for the SKY73100 is provided in
Figure 7. Figure 8 shows the package dimensions for the 38-pin
MCM and Figure 9 provides the tape and reel dimensions.
Electrostatic Discharge (ESD) Sensitivity
The SKY73100 ESD threshold level is 2500 VDC using Human
Body Model (HBM) testing. This level applies to RF signal lines
>100 MHz, analog and RF lines <100 MHz, digital lines, power
supply lines, and ground pins.
To avoid latent or visible ESD damage, always follow proper ESD
handling precautions.
