CX77107: PA Module for CDMA / PCS (1850–1910 MHz)
Applications
• Personal Communications
Services (PCS)
The CX77107 Power Amplifier Module (PAM) is a fully matched 10-pin surface mount module
developed for Personal Communications Service (PCS) and Wireless Local Loop (WLL) applications.
This small and efficient Power Amplifier packs full 1850–1910 MHz bandwidth coverage into a single
compact package. The CX77107 meets the stringent spectral linearity requirements of Code Division
Multiple Access (CDMA) PCS transmission, with high power added efficiency for power output of up to
28 dBm. A low current (VCONT) pin is provided to improve efficiency for the low RF power range of
operation.
• Wireless local loop (WLL)
Features
• Low voltage positive supply
- 3.2 V to 4.2 V
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 within the module package to optimize
efficiency and power performance into a 50 Ω 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 CX77107 is
supplied directly from a three-cell Ni-Cd, a single-cell Li-Ion, or other suitable battery with an output
in the 3 to 4 volt range. Power down is accomplished by setting the voltage on the low current
reference pin 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.
• Good linearity
• High efficiency
• Large dynamic range
• 10-pin package
- 4 mm x 4 mm x 1.5 mm
• Power down control
• Low power-state control
• InGaP
• IS95/CDMA2000
• Full U.S. PCS coverage

DATA SHEET • CX77107
Characterization Data
The graphs from Figure 2 through Figure 10 illustrate the
characteristics of a typical CX77107 power amplifier designed for
operation in the PCS frequency band (1850–1910 MHz). This
amplifier was selected by characterizing a group of devices and
choosing a part with average electrical performance for both
nominal and the full range of recommended operating conditions,
including worst case limits.
The graphs illustrate the digital signal characteristics of the
CX77107. Shown are power sweep characteristics for key
performance parameters over temperature and frequency, up to
28.5 dBm output power. The data was taken up to and including
16 dBm output power with the bias mode control pin setting of
VCONT = 2.5 volts. Beyond 16 dBm output power, the VCONT was set
to 0 volts.

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 CX77107 is capable of withstanding an MSL 3/240 °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 5 °C per second; maximum temperature
should not exceed 240 °C. If the part is manually attached,
precaution should be taken to insure that the part is not subjected
to temperatures exceeding 240 °C for more than 10 seconds. For
details on both 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–020B.

Electrostatic Discharge Sensitivity
The CX77107 is a Class I device. lists the Electrostatic Discharge
(ESD) immunity level for each pin of the CX77107 product. The
numbers in specify the ESD threshold level for each non-ground
pin where the I-V curve between the pin 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 pin, 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 pin fails the electrical
specification limits” or “the pin becomes completely non-
functional”. Skyworks employs most stringent criteria; fails
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 7.
