Description
The SKY77824-11 Power Amplifier Module (PAM) is a fully matched, 28-pad surface mount
(SMT) module developed for LTE applications. The module includes broadband coverage of FDD
LTE Bands 7 and 30, TDD LTE Bands 38/40, and Band 41 in a compact 4.0 x 3.65 mm package.
Attaining high efficiencies throughout the entire power range while meeting the stringent linearity
requirements of LTE, the SKY77824-11 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-ohm load is realized off-chip within the module package to optimize efficiency and
power performance. Silicon-on-insulator (SOI) switch follows the wideband power amplifier to
direct the RF output signal to either a band 7 duplexer or 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 (T/R1) or a shared band 38/41/7 Rx port
(T/R2). Bias for the PA MMIC and switch is generated on a CMOS IC controlled through a MIPI
RFFE interface.
The SKY77824-11 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.

Evaluation Board Description
The evaluation board (EVB) is a platform for testing and
interfacing design circuitry. To accommodate the interface testing
of the SKY77824-11, the evaluation board schematic and
assembly diagrams are included for analysis and design. Figure 2
shows the basic schematic of the EVB board and Figure 3 shows
the EVB assembly. In both views, placement of components is
shown for normal operation. Table 11 provides the bill of material
for the EVB.
