Description
The SKY77182 Power Amplifier module is a fully matched 8-pad surface mount module developed for
Wideband Code Division Multiple Access (WCDMA) applications. This small and efficient power
amplifier packs full coverage of the 1920–1980 MHz bandwidth into a single compact package. The
SKY77182 meets the stringent spectral linearity requirements of HSDPA (High Speed Downlink Packet
Access) data transmission with high power added efficiency for power output of up to 28 dBm.
Because of high efficiencies attained throughout the entire power range, the SKY77182 delivers
unsurpassed talk-time advantages.
The single Gallium Arsenide (GaAs) Microwave Monolithic Integrated Circuit (MMIC) contains all active
circuitry in the module. The MMIC includes on-board bias circuitry, as well as input and interstage
matching circuits. The output match is realized off-chip within the module package to optimize
efficiency and power performance into a 50 Ω load. This device is manufactured with Skyworks’
InGaP GaAs Heterojunction Bipolar Transistor (HBT) process that provides for all positive voltage DC
supply operation while maintaining high efficiency and good linearity. Primary bias to the SKY77182 is
supplied directly from a three-cell Ni-Cd, a single-cell Li-Ion, or other suitable battery with an output
in the 3.1 to 4.6 volt range. No VREF voltage is required. Power down is accomplished by setting the
voltage on VENABLE to zero volts. Digital bias control can be used to optimize efficiency at high and low
power or analog bias control can be used to optimize efficiency over the entire power range. No
external supply side switch is needed as typical “off” leakage is a few microamperes with full primary
voltage supplied from the battery.
