Packaging Technology
The SKY77449 Power Amplifier Module (PAM) is a fully matched, surface mount module developed for
LTE / EUTRAN applications. This small and efficient module packs full coverage of Bands XIII / XIV
LTE / EUTRAN / WCDMA into a single compact package. The SKY77449 meets the stringent spectral
linearity requirements of LTE modulation with QPSK / 16QAM modulations from 1.4 to 20 MHz
bandwidth and full or partial resource block allocations with high power added efficiency.
Integration of the PAM simplifies the design of the 4G-compatible handset radios and data cards as all
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 SKY77449 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 to 4.6 volt range, while the bias network is powered via the VCCB pad. DC-DC
converter operation can be supported with low 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.
