PRODUCT SUMMARY

SKY77441 Multi-Mode / Multi-Band PA Module for

LTE FDD Band VII (2500–2570 MHz) and

LTE TDD Bands 38 / 40 (2300–2620 MHz)

The SKY77441 Power Amplifier Module (PAM) is a fully matched, surface mount module developed

for LTE / EUTRAN FDD and TDD applications. This small and efficient module packs full coverage of

LTE FDD Band VII and LTE FDD Bands 38 / 40 into a single compact package, and is capable of

delivering the linear WCDMA power up to 28.5 dBm from 2.3 to 2.7 GHz. The SKY77441 meets the

APPLICATIONS

• Long-Term Evolution (LTE)

FDD and TDD

• Evolved Universal Terrestrial

Radio Access Networks

(EUTRAN)

stringent spectral linearity requirements of LTE modulation with QPSK / 16QAM modulations from

1.4 MHz to 20 MHz bandwidth and full or partial resource block allocations with high power added

efficiency.

• Handsets and Data Cards

Integration of the PAM simplifies the design of the 4G-compatible handset radios and data cards as

all the active RF circuitry, including the PA, input, interstage and output matching circuits and power

detector are optimized within the single module component. Output match is realized off-chip within

the module package to optimize efficiency and power performance into a 50 Ω load. The device is

manufactured with Skyworks’ BiFET process that provides for all positive voltage DC supply

operation while maintaining high efficiency and good linearity. Primary bias to the SKY77441 is

supplied via the VCC1 and VCC2 pads directly from a three-cell Ni-Cad, a single-cell Li-Ion, or other

suitable batteries with outputs in the 3.0 to 4.6 volt 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. 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 100 microamperes with full primary voltage

supplied from the battery. 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.
