- PCS 53%
• Internal ICC sense resistor for PAC
• Closed loop iPAC or open loop
operation with external PAC circuit
• Input/Output matching 50 Ω internal
(with DC blocking)

- Low profile 1.2 mm maximum
• Low APC current 20 µA
• Gold plated, lead-free contacts
The SKY77324 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.
The module consists of separate GSM850/900 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 CMOS 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 GSM850/900 bands and the other supports the DCS1800 and PCS1900 bands. Both PA
blocks share common power supply pins 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 SKY77324 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 SKY77324 also
contains band-select 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 pin selects the PA
output (DCS/PCS OUT or GSM850/900 OUT) and the Analog Power Control (VAPC) controls
the level of output power.
VBATT and VSENSE pins connect to an internal current-sense resistor and interface to an
integrated power amplifier control (iPAC™) function, which is insensitive to variations in
temperature, power supply, and process. The PAC ENABLE input allows initial turn-on of PAC
circuitry to minimize battery drain.

Electrical Specifications
The following tables list the electrical characteristics of the
SKY77324 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
SKY77324 for modes GSM850, GSM900, DCS1800, and PCS1900.
Figure 2 is a diagram of a typical SKY77324 application.
The SKY77324 is a static-sensitive electronic device and should
not be stored or operated near strong electrostatic fields. Detailed
information on device dimensions, pin descriptions, packaging
and handling can be found in later sections of this data sheet.

Electrostatic Discharge Sensitivity
The SKY77324 is a Class I device. Figure 7 lists the Electrostatic
Discharge (ESD) immunity level for each pin of the SKY77324
module. The numbers specify the ESD threshold levels for each
pin where the I-V curve between the pin and ground starts to
show degradation.
Method 3015.7 using the Human Body Model. If the magnitude of
ESD damage threshold is found to consistently exceed 2000 volts,
this so is indicated. If the ESD damage threshold below 2000 volts
is measured for either polarity, numbers are indicated that
represent worst case values observed in product characterization.
ESD testing was performed in compliance with MIL-STD-883E
Figure 7. ESD Sensitivity Areas (Top View)
Various failure criteria can be utilized when performing ESD
testing. Many vendors employ relaxed ESD failure standards,
which fail devices only after “the pin fails the electrical
specification limits” or “the pin becomes completely nonfunctional”. Skyworks’ most stringent criteria fail devices as soon
as the pin 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 5.

DATA SHEET • SKY77324
iPAC™ PAM FOR QUAD-BAND GSM / GPRS
Technical Information
Closed loop control of the amplifier is enabled when PAC ENABLE
is driven to logic high. The PA collector current will then be
directly proportional to the VAPC input voltage over the range of 400
mV to 2.1 V.
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.
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 SKY77324 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, 10–16
discrete voltage steps on the rising edge of the burst, a constant
region, 10–16 steps on the falling edge, and a final voltage.
Typically, the user defines the start, stop, and 10–16 percentage
values for each rising and falling edge, which are then applied as
discrete voltages at the VAPC input. For the SKY77324, 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
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.
Figure 8 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 pin, 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.
Figure 9 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 SKY77324 PAM may
be installed in a phone board.
Figure 10 shows an example Skyworks software interface for the
setup in Figure 9 that can be used to create a recommended DAC
ramp profile. This profile is loaded from the computer into the
Skyworks emulator board during test. The software also handles
the required PAC Enable and TX_RX control signal timing.
Figure 11 and Figure 12 show the GSM and DCS/PCS calibration
screens, respectively, called up from the ramp profile interface in
Figure 10. These calibrations, done for each PAM, generate an
output power versus VAPC curve from sample data. Points from this
curve are combined with the ramp coefficients to generate the
DAC ramp during handset operation or test.

Open Loop Control Mode
With PAC ENABLE at a logic low, the voltage applied to VAPC is
buffered and applied directly to the bases of the RF devices. This
mode of operation provides backward compatibility with the
existing amplifier designs and allows for various test scenarios. As
with previous designs, an active clamp acts as a protection
mechanism limiting the maximum voltage that can be applied to
the base of the RF devices. This clamp voltage decreases with
increasing supply voltage.
The enable threshold on the VAPC input for open loop operation
exhibits a wide tolerance, which may vary from 200 mV to
800 mV. When enabled in Open Loop mode, the internal PAC
circuitry (V-I converter and integrator) is placed in standby.
