Technical Description
The SKY65342-11 provides input and output amplifier stages, and
is internally matched for optimum efficiency. An active bias circuit
provides the input and output stages with excellent gain tracking
over temperature and voltage variations. The module operates
with positive DC voltages, and maintains high efficiency and good
linearity. The nominal operating voltage is 3.6 V for maximum
power, but the device can be operated at slightly lower voltages
for other mobile applications.
The input and output stages are independently supplied using the
VCC1 and VCC2 supply lines (pins 12 and 10, respectively). The
bias reference voltages for stages 1 and 2 are supplied using
common lines VREF1 and VREF2 (pins 5 and 6, respectively). The
DC control voltage that sets the bias for stages 1 and 2 is
supplied by the VC_BIAS signal, pin 4.
Electrical and Mechanical Specifications
Signal pin assignments and functional pin descriptions are
described in Table 1. The absolute maximum ratings of the
SKY65342-11 are provided in Table 2. The recommended
operating conditions are specified in Table 3 and electrical
specifications are provided in Table 4.
Typical performance characteristics of the SKY65342-11 are
illustrated in Figures 3 through 7. The state of the SKY65342-11
is determined by the logic provided in Table 5.
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 SKY65342-11 is rated to Moisture Sensitivity Level 3 (MSL3)
at 260 qC. It can be used for lead or lead-free soldering. For
additional information, refer to Skyworks Application Note, PCB
Design and SMT Assembly/Rework Guidelines for MCM-L
Packages, document number 101752.
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 Information – RF Modules,
