DATA SHEET
SKY77318 iPAC™ PAM for Quad-Band GSM / GPRS
Applications
Description
• Quad-Band cellular
handsets encompassing
- Class 4 GSM850/900
- Class 1 DCS1800/
PCS1900
- Class 12 GPRS multi-slot
operation
The SKY77318 Power Amplifier Module (PAM) is designed in a low profile (1.2 mm), compact form
factor for quad-band cellular handsets comprising GSM850/900, DCS1800, and PCS1900 operation.
The PAM also supports Class 12 General Packet Radio Service (GPRS) multi-slot operation.
Features
• Low input power range
- 0 to 6 dBm
• High efficiency
- CELL 58%
- GSM 56%
- DCS 56%
- PCS 56%
• BiCMOS PA controller and
interface IC
- Low power control slope
- Fast response time
- Improved control
accuracy
• Integrated closed loop
power amplifier control
The module consists of separate GSM PA and DCS1800/PCS1900 PA blocks, impedance-matching
circuitry for 50 Ω input and output impedances and a Power Amplifier Control (PAC) block with an
internal current-sense resistor. The custom BiCMOS integrated circuit provides the internal PAC
function and interface circuitry. Fabricated onto a single Gallium Arsenide (GaAs) die, one
Heterojunction Bipolar Transistor (HBT) PA block supports the GSM bands and the other supports the
DCS1800 and PCS1900 bands. Both PA blocks share common power supply pads to distribute
current. The GaAs die, the Silicon (Si) die, and the passive components are mounted on a multi-layer
laminate substrate. The assembly is encapsulated with plastic overmold.
RF input and output ports of the SKY77318 are internally matched to a 50 Ω load to reduce the
number of external components for a quad-band design. Extremely low leakage current (2.5 μA,
typical) of the dual PA module maximizes handset standby time. The SKY77318 also contains bandselect switching circuitry to select GSM (logic 0) or DCS/PCS (logic 1) as determined from the Band
Select (BS) signal. In Figure 1 below, the BS pad selects the PA output (DCS/PCS_OUT or GSM_OUT)
and the Analog Power Control (VAPC) controls the level of output power.
The VBATT pad connects to an internal current-sense resistor and interfaces to an integrated power
amplifier control (iPAC™) function, which is insensitive to variations in temperature, power supply,
process, and input power. The ENABLE input allows initial turn-on of PAM circuitry to minimize battery
drain.

DATA SHEET
SKY77318 iPAC™ PAM FOR QUAD-BAND GSM / GPRS
Electrical Specifications
The following tables list the electrical characteristics of the
SKY77318 Power Amplifier Module. Table 1 lists the absolute
maximum ratings and Table 2 shows the recommended operating
conditions. Table 3 lists the electrical characteristics of the
SKY77318 for modes GSM, DCS1800, and PCS1900. Figure 2 is a
diagram of a typical SKY77318 application.
The SKY77318 is a static-sensitive electronic device and should
not be stored or operated near strong electrostatic fields. Detailed
information on device dimensions, pad descriptions, packaging
and handling can be found in later sections of this data sheet.

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 SKY77318 is capable of withstanding an MSL3/260 °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 260 °C. If the part is manually attached,
precaution should be taken to insure that the part is not subjected
to temperatures exceeding 260 °C for more than 10 seconds. For
details on attachment techniques, precautions, and handling
procedures recommended by Skyworks, please refer to Skyworks
Application Note: PCB Design and SMT Assembly/Rework,
Document Number 101752. Additional information on standard
SMT reflow profiles can also be found in the JEDEC Standard
J-STD–020.

Electrostatic Discharge Sensitivity
The SKY77318 has been classified as a Human Body Model Class
1C (1000 volts to < 2000 volts) and Machine Model Class M2
(100 volts to < 200 volts) device. ESD testing has been performed
in compliance to the latest JEDEC Human Body Model
specification, HBM (JESD22-A114-B) and Machine Model
specification, (JESD22-A115-A). A report summarizing the ESD
testing, including ESD failure level thresholds on each pad-toground and pad-to-pad combination, may be obtained upon
request.
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 below.

DATA SHEET
SKY77318 iPAC™ PAM FOR QUAD-BAND GSM / GPRS
Technical Information
Closed loop control of the amplifier is enabled when ENABLE is
driven to logic high. The PA collector current will then be directly
proportional to the VAPC input voltage over the range of 200 mV to
2.1 V.
acceptable spectral limits at specified offset frequencies. The VAPC
input has an internal reconstruction filter such that external
resistors or capacitors are unnecessary on the phone board or the
test fixture.
To meet the GSM power versus time mask and switching transient
requirements the PAM must be provided with a DAC ramp profile
on the VAPC input as well as proper timing on digital controls for the
PAC circuitry.
Figure 7 represents the dynamic characteristics of the RF output
burst power that results from the ramp profile delivered by the
DAC to the VAPC input. The transmit power must not exceed the
given limits at the time specified relative to the start and end of
the data burst. Additional requirements are placed on spectral
components generated by switching transients. Ramping at high
rates will result in components that violate these spectral limits. A
ramp control signal must be applied to the VAPC pad, which results
in the desired power ramp response. The log relationship of VAPC
to POUT, along with the finite bandwidth and potential slew rate
limitations of the feedback loop, results in a complex mapping of
the ramp profile to the actual output power. Careful attention is
required in generating the input waveform which results in the
desired output response.
Note:
Please refer to 3GPP TS 51.010-1: Mobile Station (MS)
conformance specification. All GSM specifications
are now the responsibility of 3GPP. The standards
are available at http://www.3GPP.org.
The SKY77318 has been designed to comply with interface
requirements and DAC resolution of leading base band devices.
The ramp profile typically consists of a pedestal voltage, 10 to 16
discrete voltage steps on the rising edge of the burst, a constant
region, 10 to 16 steps on the falling edge, and a final voltage.
Typically, the user defines the start, stop, and 10 to 16 percentage
values for each rising and falling edge, which are then applied as
discrete voltages at the VAPC input. For the SKY77318, generally
the same profile, scaled in amplitude, is used for all frequencies
and power control levels. The ultimate purpose is to keep the RF
output power ramp within the time mask and to maintain
Figure 8 shows an example of the Skyworks PAM test setup for
evaluation of RF performance with various ramp profiles. The
user’s test setup may also include a TX/RX switch and a diplexer
in the output signal path. Alternatively, the SKY77318 PAM may
be installed in a phone board.
