Description
The SKY77768 Power Amplifier Module (PAM) is a fully matched 10-pad surface mount module
developed for Wideband Code Division Multiple Access (WCDMA) applications. This small and efficient
module packs full 880-915 MHz bandwidth coverage into a single compact package. Because of high
efficiencies attained throughout the entire power range, the SKY77768 delivers unsurpassed talk-time
advantages. The SKY77768 meets the stringent spectral linearity requirements of High Speed
Downlink Packet Access (HSDPA), High Speed Uplink Packet Access (HSUPA), and Long Term
Evolution (LTE) data transmission with high power added efficiency. An integrated directional coupler
eliminates the need for any external coupler.
The Gallium Arsenide (GaAs) Microwave Monolithic Integrated Circuit (MMIC) contains all amplifier
active circuitry, including input and interstage matching circuits. The silicon CMOS support die,
providing precision biasing for the MMIC affords a true CMOS-compatible control interface. Output
match into a 50-ohm load, realized off-chip within the module package, optimizes efficiency and
power performance.
The SKY77768 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. While primary bias to the SKY77768 can be supplied directly from any suitable battery
with an output of 3.2 V to 4.2 V, optimal performance is obtained with VCC2 sourced from a DCDC
power supply adjusted within 0.5 V to 3.6 V based on target output power levels. Power down
executes by setting VENABLE to zero volts. No external supply side switch is needed as typical "off"
leakage is a few microamperes with full primary voltage supplied from the battery.

ACLR is expressed as a ratio of total adjacent power to WCDMA modulated in-band, both measured in 3.84 MHz bandwidth at specified offsets.
LTE: EVM and ACLR are measured with QPSK modulation with 1.4 MHz bandwidth and
5
resource blocks. (Maximum Power Reduction = 0 dBm per 3GPP TS36.101.
MPR is the maximum power reduction as defined in 3GPP TS36.101
All phases, time = 10 seconds.
