Description
The SKY77781-11 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 SKY77781-11 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 Ω 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 SKY77781-11 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.
