Description

The SKY77733 SkyHi™ Power Amplifier Module (PAM) is a fully matched, surface mount module

developed for LTE applications. This small and efficient module packs full coverage of LTE Bands

13/14 into a single compact package. The SKY77733 meets the stringent spectral linearity

requirements of LTE modulation with QPSK / 16QAM modulations from 5 MHz to 10 MHz bandwidth

and full or partial resource block allocations with high power added efficiency.

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

SKY77733 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 3.0 to 4.5 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

VMODE0 and VMODE1 pads are used to switch between high, medium and low power modes to

reduce current consumption and gain in the back-off conditions.
