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.
