PRODUCT SUMMARY
SKY77708 Power Amplifier Module for LTE / EUTRAN
Bands XIII / XIV (777–798 MHz)
Applications
Description
• Long-Term Evolution (LTE)
The SKY77708 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 LTE Bands XIII / XIV
into a single compact package. The SKY77708 meets the 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.
• Evolved Universal
Terrestrial Radio Access
Networks (EUTRAN)
• Handsets and Data Cards
The single Gallium Arsenide (GaAs) Microwave Monolithic Integrated Circuit (MMIC) contains all active
circuitry in the module, including the PA, input, and interstage matching. Output match is realized off-
chip within the module package to optimize efficiency and power performance into a 50 Ω load. The
SKY77708 is manufactured with Skyworks’ BiFET process which provides for all positive voltage DC
supply operation while maintaining high efficiency and good linearity. Primary bias is supplied via the
VCC1 and VCC2 pads directly from battery output in the 3.2 to 4.2 volt 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 a few microamperes with full primary voltage supplied from the battery. The
VMODE_0 and VMODE_1 pads are used to switch between high, medium and low power modes to
reduce current consumption and gain in the back-off conditions.
