PRODUCT SUMMARY

SKY77445 Front-End Module for LTE / EUTRAN

Band VII (Tx 2500-2570 MHz), (Rx 2620-2690 MHz)

Applications

Description

• Long-Term Evolution (LTE)

The SKY77445 Front-End Module (FEM) is a fully matched, 16-pad surface mount module

developed for LTE/EUTRAN applications. Small and efficient, this LTE FEM integrates the

interstage filter, input and output matching, power amplifier, power detection, and duplexer

into a single 4 mm x 7 mm x 1.1 mm package.

• Evolved Universal Terrestrial Radio

Access Network (EUTRAN)

• Handsets and Data Cards

The SKY77445 meets the stringent spectral linearity requirements of LTE with QPSK / 16QAM

modulations from 1.4 MHz to 20 MHz bandwidth and full or partial resource block allocations

with high power added efficiency. The FEM incorporates Inter-Stage Filter and Duplexer,

InGaP BiFET PA, and output power detector.

Features

• QPSK, 16QAM, 64QAM modulations

• Up to 20 MHz bandwidths

• Up to 100 resource blocks

Integration of the RF front-end greatly simplifies the design of the 4G-compatible handset

radio or data card as all critical matching between the interstage filter, PA, power detection,

and duplexer is optimized within the single module component. By optimizing the efficiency

of the InGaP BiFET PA MMIC, reducing RF loss between the integrated components and

within the Duplexer itself, and improving the match between the PA and the Duplexer, this

FEM achieves low current at maximum output power that significantly reduces the power

dissipated in the LTE-enabled handsets or data cards.

• Linear power at 3.3 V:

- 25 dBm LTE

- 26 dBm WCDMA

• Duplexer Tx-Rx attenuation and

isolation: 49 dB

• Integrated Power Detector,

interstage filter and duplexer

• Low voltage positive bias supply:

3.0 V to 4.6 V

Primary bias to the SKY77445 is supplied via the VCC1 and VCC2 pads directly from a three-

cell Ni-Cad, a single-cell Li-Ion, or other suitable battery with output in the 3.0 V to 4.6 V

range, while the bias network is powered up with the VCCB pad. DC-DC converter operation

can be supported with lower power operation down to 1.5 V.

• Supports low collector voltage

operation down to 1.5 V

• Excellent linearity, efficiency

• Large dynamic range

Power down is accomplished by setting a logic low level on the VEN pad. No external supply

side switch is needed as typical “off” leakage is 10 μA with full primary voltage supplied

from the battery (V^BA= 0 V). The VMODE pad is used to switch between high and low power

modes to reduce current consumption and gain in the back-off conditions. VBA is used to

further control the current consumption in the low power mode.

• Low Profile 16-pad package:

4 mm x 7 mm x 1.1 mm

• Analog bias current control in low

power mode using VBA pad

• InGaP BiFET technology

This small package uses Skyworks’ low cost, multi-laminate substrate technology and is

approximately half the size of individually packaged component solutions. The SKY77445

front-end module can save handset and data card designers significant board space and

design-cycle time, and significantly simplify supply chain and sourcing of RF components.
