ADVANCE DATA SHEET
SKY77435 Front-End Module for WCDMA / HSDPA / HSUPA
(Tx 1710-1770 MHz), (Rx 2110-2170 MHz)
Applications
Description
• Digital cellular (WCMDA)
handsets
The SKY77435 Front-End Module (FEM) is a fully matched, 16-pad surface mount module developed
for WCDMA applications. Small and efficient, this WCDMA FEM integrates the interstage filter, the
input matching, the power amplifier, the output matching, the power detection, and the duplexer into
a single 7 mm x 4 mm x 1.1 mm package.
Features
• High Speed Downlink
Packet Access (HSDPA)
• High Speed Uplink Packet
Access (HSUPA)
• Low quiescent current
- 20 mA
• Low current consumption
- 530 mA
• Integrated Power Detector
• 16-pad package
• Small profile
- 7 mm x 4 mm x 1.1 mm
• Low voltage
- 3.1 V–4.45 V
The SKY77435 meets the stringent spectral requirements of HSDPA standards up to 25.2 dBm output
power. The FEM incorporates an InGaP HBT PA and contains circuitry to optimize power detector
performance. Different control pads are available to enhance the performance of the FEM at different
power levels.
Integration of the RF front-end greatly simplifies the design of the handset radio as all critical
matching between the interstage filter, PA, power detection, and duplexer is optimized within the
module. By optimizing the efficiency of the InGaP HBT PA MMIC and reducing the RF loss between
the integrated components, this FEM achieves current as low as 450 mA at maximum output power
(25.2 dBm) that significantly improves the talk time of the WCDMA handset. This small package uses
Skyworks’ low cost, multi-laminate substrate technology and is approximately half the size of
individually packaged component solutions. The SKY77435 front-end module can save handset
designers significant board space and design-cycle time.
• Digital enable pad
• Highly integrated, user
friendly solution
• InGaP HBT
• Integrated interstage filter
and duplexer
• Requires few external
components

The SKY77435 is a multi-layer laminate base, overmold
encapsulated modular package designed for surface-mounted
solder attachment to a printed circuit board. Figure 4 is a
mechanical drawing of the pad layout for this package. Figure 5
provides a recommended phone board layout footprint for the FEM
to help the designer attain optimum thermal conductivity, good
grounding, and minimum RF discontinuity for the 50 ohm
terminals.

Package Description
Figure 6 shows each pad name and the pad numbering
convention, which starts with pad 1 in the upper left, as indicated
and increments counter-clockwise around the package. Figure 7
illustrates typical case markings.
The SKY77435 is currently qualified for MSL3/260 °C. 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.
Production quantities of this product are shipped in the standard
tape-and-reel format. For packaging details, refer to Skyworks

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.
