Skyworks offers lead
(Pb)-free "environmentally
friendly" packaging
that is RoHS compliant
(European Parliament
for the Restriction of
Hazardous Substances).
The SKY77162 System Smart® Power Amplifier Module (PAM) is a fully matched, 8-pad, surface
mount module developed for Code Division Multiple Access (CDMA), Advanced Mobile Phone Service
(AMPS) and Wireless Local Loop (WLL) applications in the 824–849 MHz bandwidth. This small and
efficient module packs full bandwidth coverage into a single compact package.
The SKY77162 meets the stringent IS95 CDMA linearity requirements to and exceeding 28 dBm
output power, and can be driven to levels beyond 31 dBm for high efficiency in FM mode operation. A
low current pad (VCONT) provides improved efficiency for the low RF power range of operation.
The single Gallium Arsenide (GaAs) Microwave Monolithic Integrated Circuit (MMIC) contains all active
circuitry in the module. The MMIC contains on-board bias circuitry, as well as input and interstage
matching circuits. The output match is realized off-chip and within the module package to optimize
efficiency and power performance into a 50-ohm load. This device is manufactured with Skyworks’
GaAs Heterojunction Bipolar Transistor (HBT) process that provides for all positive voltage DC supply
operation while maintaining high efficiency and good linearity. Primary bias to the SKY77162 is
supplied directly from a three-cell Ni-Cd, a single-cell Li-Ion, or other suitable battery with an output
in the 3.2 to 4.2 volt range. Power down is accomplished by setting the voltage on the low current
reference pad to zero volts. No external supply side switch is needed as typical “off” leakage is a few
microamperes with full primary voltage supplied from the battery.

Package and Handling Information
Because of its sensitivity to moisture absorption, this device
package is baked and vacuum-packed prior to shipment.
Instructions on the shipping container label must be followed
regarding exposure to moisture after the container seal is broken,
otherwise, problems related to moisture absorption may occur
when the part is subjected to high temperature during solder
assembly.
The SKY77162 is capable of withstanding an MSL3/250 °C solder
reflow. Care must be taken when attaching this product, whether
it is done manually or in a production solder reflow environment.
If the part is attached in a reflow oven, the temperature ramp rate
should not exceed 3 °C per second; maximum temperature
should not exceed 250 °C. If the part is manually attached,
precaution should be taken to insure that the part is not subjected
to temperatures exceeding 250 °C for more than 10 seconds. For
details on both attachment techniques, precautions, and handling
Electrostatic Discharge Sensitivity
The SKY77162 is a Class 2 device. Figure 15 lists the Electrostatic
Discharge (ESD) immunity level for each non-ground pad of the
SKY77162 product. The numbers in Figure 15 specify the ESD
threshold level for each pad where the I-V curve between the pad
and ground starts to show degradation.
The ESD testing was performed in compliance with
MIL-STD-883E Method 3015.7 using the Human Body Model. If
ESD damage threshold magnitude is found to consistently exceed
2000 volts on a given pad, this so is indicated. If ESD damage
threshold below 2000 volts is measured for either polarity,
numbers are indicated that represent worst case values observed
in product characterization.
Various failure criteria can be utilized when performing ESD
testing. Many vendors employ relaxed ESD failure standards,
which fail devices only after “the pad fails the electrical
specification limits” or “the pad becomes completely non-
functional”. Skyworks employs most stringent criteria and fails
devices as soon as the pad begins to show any degradation on a
curve tracer.
To avoid ESD damage, both latent and visible, it is very important
that the product assembly and test areas follow the Class-1 ESD
handling precautions listed in Table 4.
