Description
The SKY77814-11 Power Amplifier Module (PAM) is a fully
matched, 24-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, and Band 41 in a
compact 3.0 x 4.0 mm package. Attaining high efficiencies
throughout the entire power range while meeting the stringent
linearity requirements of LTE, the SKY77814-11 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. A silicon-on-
insulator (SOI) switch following the wideband power amplifier
directs the RF output signal to either a band 7 duplexer or to one
of three TDD filters supporting bands 38, 40, and 41. Additional
throws in the SOI switch allow the reuse of TDD filters in Rx mode
by providing paths to either the band 40 Rx port or a shared band
38/41 Rx port. Biasing for the PA MMIC and switch is generated
on a CMOS IC controlled through a MIPI RFFE interface.
The SKY77814-11 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. No external supply side switch is required
as typical "off" leakage is a few microamperes.
