Description
The SKY77778-51 Power Amplifier Module (PAM) is a fully matched, 10-pad surface mount (SMT)
module developed for LTE applications. The module includes broadband coverage of LTE FDD Bands
7 and 30, LTE TDD Bands 38, 40, 41, and AXGP Band in a compact 2.0 mm x 2.5 mm package.
Attaining high efficiencies throughout the entire power range while meeting the stringent linearity
requirements of LTE, the SKY77778-51 delivers unsurpassed savings in current consumption for
data-intensive applications.
The Gallium Arsenide (GaAs) Microwave Monolithic Integrated Circuit (MMIC) contains all amplifier
active circuitry, including input, interstage, and output matching circuits. Output match into a 50-ohm
load, realized off-chip within the module package, optimizes efficiency and power performance. The
silicon CMOS support die, providing precision biasing for the MMIC affords a true CMOS-compatible
control interface.
The SKY77778-51 is manufactured with Skyworks' InGaP GaAs Heterojunction Bipolar Transistor
(HBT) process which provides for all positive voltage DC supply operation and maintains high
efficiency and good linearity. Optimal performance is obtained with VCC1 and VCC2 sourced from a
DC-DC power supply based on target output power levels. No external supply side switch is needed
as typical "off" leakage is a few microamperes.
